X2 + 13x + 36= 0
need the answer to this equation

Step-by-step explanation:

x^2 + 13x + 36 = (x+4)(x+9)

x = -4 or x = -9

Step-by-step explanation:

x² + 13x + 36= 0

x² + 4x + 9x + (9*4)= 0

x*(x + 4) + 9*(x + 4) = 0

(x+4) (x +9) =0

x + 4 = 0      or  x + 9 = 0

  x = -4         ;            x = -9

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
