Only answer if yk it ! correct answer ill mark as brainliest!

Solve the equation for all values of x by completing the square:
x^2+45=-14x

x=-5, x=-9

Step-by-step explanation:

x^2+45=-14x

add 14x to both sides

x^2+45+14x=-14x+14x

simplify

x^2+14x+45=0

solve using quadratic formula

a=1, b-14, c=45

x=-14±√14^2-4·1·45/2·1

(solve using a calculator or PEMDAS)

(solve for both + and -)

x=-5, x=-9

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.'
