Equations with an order of 2 (contains a value to the power of 2, i.e. x2).
An example of a quadratic equation is:
x2 + 10x + 7
If you're talking about two linear equations, make sure they are not parallel. If you're talking about quadratics, make sure that b2-4ac is not negative.
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.
X^2 - 2X - 48 = 0 what two factors of - 48 add up to - 2 ? (X + 6)(X - 8) X = - 6 --------- X = 8 ---------by inspection can solve many quadratics
The end behavior of a quadratic function differs from that of a linear function due to their respective degrees and shapes. A quadratic function, which is a polynomial of degree two, has a parabolic graph that opens upwards or downwards, leading to both ends of the graph either rising or falling indefinitely. In contrast, a linear function has a constant slope and produces a straight line, causing its ends to extend infinitely in opposite directions. Thus, while quadratics demonstrate a U-shaped behavior, linear functions maintain a consistent directional trend.
The simplest example that fits that is y = x^2 - 7x + 12. A math professor wouldn't like the process, but assuming we want a positive quadratic, and since positive quadratics are symmetrical along their minimums, we can skip some steps. We know that the local minimum is going to lie exactly between 3 and 4, at x = 7/2. Put everything on one side to get 2x - 7 = 0. Taking the integral (and skipping a few more steps) gets y = x^2 - 7x + c. Solving for c where y = 0 when x = 3, we find c = 12.
x2=100
Quadratics that can be written in the form y = a*(x - r)2
they're not
1. Quadratics should always contain a set of numbers inconjuction with letters (x usually). 2. Quadratics are always in the form ax2 + bx + c. Where a,b and c are constants and x is a variable. 'a' must always equal '0'. 3. The total equation must never equal '0'. 4. To solve quadratics, you DO NOT factorise. 5. To solve quadratics, use the formula x=a, therefore, b=c. 6. The word 'quadratics' literally means four. This in term means that there are four ways you can solve for the answer of the equation.
In rationalising quadratics 2a3 - 5a2 - 39 is an irrelevance. It is not a quadratic but a cubic and so not within the defined scope.

Quadratics can two, one or no real roots.
Evariste Galois worked on quadratics when he was a teenager. He was able to establish the means to solve quadratics using radicals and laid the ground work for what became Galois theory. Unfortunately, he died when he was only 20 years old during a duel.

I am actually doing a project on quadratics right now. what i have learned is that quadratics are used alot in sports like golf to measure like the curve of a golf ball and they are alos used in buissness and higher math. I couldn't find alot of information about how they were used in real worl scenarios so i focused more on how porabala's are used in architecture, for example i said that the mccdonalds sign is two porabala's put together. This is the pbest i could do !
