Solve for x in the equation x squared + 20 x + 100 = 36

x = - 16, x = - 4

Step-by-step explanation:

Given

x² + 20x + 100 = 36 ( subtract 36 from both sides )

x² + 20x + 64 = 0

Consider the factors of the constant term (+ 64) which sum to give the coefficient of the x- term (+ 20)

The factors are 16 and 4, since

16 × 4 = 64 and 16 + 4 = 20, thus

(x + 16)(x + 4) = 0

Equate each factor to zero and solve for x

x + 16 = 0 ⇒ x = - 16

x + 4 = 0 ⇒ x = - 4

the answer is 48m^2!

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
