x2-2x = 63
x2-2x -63 = 0 => x = -7 or x = 9
So x must = 9
Check: 92-18 = 63

Is b squared-4ac called simplest form?
No, it is the discriminant of a quadratic equation.
Is x plus y2 equals 25 a linear equation?
No, not if the y is squared. When graphed the equation will not form a straight line.
What is an equation that can be expressed in the form of the equation y equals ax squared plus bx plus c where the variable 'a' is not equal to 0?
The equation ax2 + bx + c = 0, where a != 0 is called quadratic.
Why quadratic equation called quadratic?
Because it is in the form of ax^2+bx+c=0 Because quadratic means squared hence ax squared + bx +c=0 has a squared number as it's highest term. This is in fact the area of a square of a side "x" is x^2, so every equation having variable with exponent 2 become quadratic equation.
A way to write numbers by showing the value of each digit?
expanded form

What is the exponent form of fifty squared and the value?
It is 22*54 = 2500.
How do you factor 7x cubed - 12x squared - 4x?
First, you remove every x that you can from the equation. Next, you reach the simplest form of the equation, which is (7x-2)(x-2). Which is the lowest factorable form.

What is the form of an equation for a horizontal line?
For a horizontal line, it is y= a value
The vertex form of the equation of a parabola is y x-5 2 plus 16 what is the standard form of the equation?
In the equation y x-5 2 plus 16 the standard form of the equation is 13. You find the answer to this by finding the value of X.
The value obtained when an equation is used to calculate the amount of product that will form during a reaction?
The value obtained when an equation is used to calculate the amount of product that will form during a reaction is called THE THEORETICAL YIELD.

Quadratic equation definition?
An equation of the second degree, meaning it contains at least one term that is squared.
How do you graph x squared plus y squared equals 15?
1st rearrange the equation so that it is in the form Y = . . . . .Then substitute in values for X (use whole numbers) and use the equation to calculate the value of Y (not Y squared).Then plot these numbers against each other (X and Y) on your graph.Remember that you also need to include negative values for X and when taking a square root the answer can be plus or minus (plot both), if you do enough examples you'll see a pattern forming
