X^2 - 2x - 63 = 0 Which value is a solution to the given equation?
A:-7
B:-2
C:0
D:63

Step-by-step explanation: When an equation has a squared term in it

such as x² - 2x - 63 = 0, it's called a polynomial equation.

The rule for solving a polynomial equation is

to first set it equal to 0, them factor.

Since this equation is already set equal to 0, we can factor the left side.

To factor x² - 2x - 63, look for factors of -63 that add to -2.

In this case, these factors are -9 and +7.

So we have (x - 9)(x + 7) = 0.

When two terms are multiplying together to equal 0,

either one term or the other must equal 0.

So x - 9 = 0 or x + 7 = 0.

Solving for x in each equation, we get x = 9 or x = -7.

So this equation has two solutions and we write out answer

in set notation which looks like this {9, -7}.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
