The first step to solve a quadratic expression that's not set to zero is to solve the equation so that it is set to zero:

x² - 5x - 32 = -3x + 3
x² - 5x - 32 - 3 = -3x
x² - 5x + 3x - 35 = 0
x² - 2x - 35 = 0

Next, factor the quadratic equation:

x² - 2x - 35 = 0
(x + 5)(x - 7) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (x + 5) or (x - 7) must equal zero:

If (x + 5) = 0, x must equal -5
If (x - 7) = 0, x must equal 7

So the solution is that x = -5 or 7

The volume of a cube is height x length x width:

v = h x l x w
v = 1 x 4 x 9
v = 36

The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:

c² - 15c + 54 = 0
(c - 6)(c - 9) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (c - 6) or (c - 9) must equal zero:

If (c - 6) = 0, c must equal 6
If (c - 9) = 0, c must equal 9

So the solution is that c = 6 or 9

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

2a⁷ - 3a⁷ = -1a⁷

The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)² : a = π r².
