What is the Meaning of algebraic equation?
An equation cannot exist (has no meaning) without an '=' sign. Therefore, and somewhat simplistically, an equation MEANS that, for specific instances, the entities on both sides of the '=' sign are in balance (equal in worth). Example 1: x + 2 = 5; means there is a value of 'x' which when substituted into the entity 'x + 2' will make it equal in value to what's on the other side of '=', ie: 5. In this example the balance is achieved when and only when x has the value 3. Example 2: x2 + 5x - 8 = 66 (where x2 represents x-squared) means there are > 1 value of 'x' which when substituted into the entity 'x2 + 5x - 8' wll make it equal in value to 66. In this example the values of x ('+' and '-'values) can be determined iteratively or by using the quadratic formula. Hope this helps.
How do you factor 2x squared minus 13x plus 15?
This is a quadratic equation, and so you it falls under the rule: ax squared + bx + c. This means you need to times the 2x squared by 15, which is 30. Then you need to find the factors of thirty, i.e. 3 and 10, 15 and 2, 5 and 6. You need to find the pair of factors that add to make -13x, which would be -3 and -10. you then need to put these into the equation - it would become 2x squared -10x (as one equation) and -3x +15 would be another equation. we can see that 2x squared and -10x have 2x in common, and so the answer for that would be 2x (x - 5). the second equation would be -3 (x - 5). the two equations have x - 5 in common, and that would make up the first set of brackets. you then add the rest (2x - 3) and your answer would be (x - 5) (2x - 3).
What is the answer to x equals 36?
36=36The "answer" is the number that ' x ' must be in orderto make the equation a true statement.The answer to this equation is: 36 .
How many yards of fabric are needed to make a 70 inch round table cloth?
You need at least 4 yards of fabric to make a 70 inch round table cloth. Most people would use close to 6 yards to make the designs that they'd like to.

What is the solving for the roots of quadratic equation?
It is finding the values of the variable that make the quadratic equation true.
Why are x values called roots?
In math speak: Solving the equation means finding 'x' values that make the equation true. These 'x' values are called the roots of the quadratic.
What shape does the quadratic graph make?
The graph of a quadratic equation has the shape of a parabola.
What adds together to make -9 but times together to make 4?
The numbers are: -0.4688 and -8.5312 to 4 decimal places More accurate values can be found by using the quadratic equation formula
What is quadratic functions?
It is a quadratic equation that normally has two solutions
What are 3 different methods that can graph a linear equation?
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
Which values for a b or c can you not use the quadratic equation?
a = 0. That is because a = 0 implies that there is no quadratic term and so the equation is not a quadratic!There may be some who make claims depending on the value of the discriminant (which is b2-4ac). That is true only for elementary mathematics. In more advanced mathematics (complex analysis), the quadratic equation can be used in all cases except when a = 0: the value of the discriminant is irrelevant.a = 0.

Where do you find the roots when looking at a parabola?
-- The roots of a quadratic equation are the values of 'x' that make y=0 . -- When you graph a quadratic equation, the graph is a parabola. -- The points on the parabola where y=0 are the points where it crosses the x-axis. -- If it doesn't cross the x-axis, then the roots are complex or pure imaginary, and you can't see them on a graph.
How do engineers use the quandratic formula?
Law of motion is quadratic equation and is use in calculate of object trajectory. Fluid dynamic for sizing of pump is also second order equation. Quadratic equation or higher may use to fit equation for fast calculation of result. Example on vapour density equation for the use of evaporative mass transfer. We do need to know how much water air can take. It could use the data from table but the work will be lengthly. We can make data in the table a form of polynomial equation and so put it into program for calculated out this require vapour density.
