in quadratic equation it must be in standard form, ax^2 + bx + c = 0.
Jenny is five years older than Marian. In three years, the product of her age and Marian's age five years ago will be 90 years. Find their present age.
Solution:
Let x= Marian's present age
x + 5= Jenny's present age

How are quadratic equations used in real life?
Many real life physics problems are parabolic in nature. Parabolas can be shown as a quadratic equation. If you have two variables then usually you can use the equation to find the best solution to a problem. Also, it is a beginning in the world of mathematical optimization. Some equations use more than two variables and require the technique used to solve quadratics to solve them. I just ran an optimization of 128 variables. To understand the parameters I needed to set I had to understand quadratics.

What is the solution to the math problem involving the keyword "quadratic equation"?
The solution to a math problem involving a quadratic equation is the values of the variable that make the equation true, typically found using the quadratic formula or factoring.
Do all quadratic equations have two solutions?
I may only be in 8th grade but I am absolutely positive that all quadratic equations have 2 solutions. No - They may have 0,1, or 2 answers For example, the problem x^2 + 8x +16 = 0 has only one solution -4. This is because the radical evaluates to 0 rendering the +/- sign irrelevant.

How do you write a word problem involving a quadratic function. How would you explain the steps in finding the solution?
To write a word problem involving a quadratic function, start by identifying a real-world scenario that can be modeled by a quadratic relationship, such as projectile motion or area optimization. Frame the problem by describing the situation, including key variables and relationships, and use specific numbers to make it concrete. To find the solution, set up the quadratic equation based on the problem context, apply techniques like factoring, completing the square, or using the quadratic formula, and interpret the results in the context of the original scenario. Finally, check if the solutions make sense within the problem’s constraints.
How do you apply quadratic equations in life?
Quadratic equations can be applied in various real-life situations, such as optimizing business profits, where they help identify maximum revenue points based on pricing strategies. They are also used in physics to model the trajectory of objects, like projectiles, allowing for calculations of height and distance. Additionally, quadratic equations are relevant in finance for calculating areas of investment returns or in architecture for designing parabolic structures. Overall, they provide valuable tools for problem-solving in diverse fields.
How would you use simplifying quadratic equations in real life?
Engineers and mathematicians apply the simplifying of all manner of equations every day in the course of their work. Scientists in several fields may be required to do the same in the course of a particular project or problem.
Why can there be extraneous solutions in a logartithmic equation?
Extraneous solutions turn up in a few different p;aces in algebra. One reason they turn up in logarithmic equations is that you can only have a log of a positive number, but when you solve the equation, one of the answers is negative. Did you ever do a word problem about a rectangle and have to solve a quadratic equation? You probably got 2 answers, and had to reject one of them because the length of a rectangle can't be negative. Same idea: the algebra doesn't understand what the problem is about, it just churns out answers!
How do you solve word problems involving measurements?
To solve word problems involving measurements, first read the problem carefully to understand what is being asked and identify the relevant measurements. Next, convert any units if necessary to ensure consistency, and then create equations or expressions based on the information provided. Finally, solve the equations step by step, and double-check your work to ensure that the solution makes sense in the context of the problem.
How do you solve complex cases of quadratic equations?
If the discriminant - the part under the radical sign in the quadratic formula - is negative, then the result is complex, it is as simple as that. You can't convert a complex number to a real number. If a particular problem requires only real-number solutions, then - if the formula gives complex numbers - you can state that there is no solution.
Once you have reduced a polynomial to a quadratic function you can always use the quadratic formula to finish the problem?
