Find the solution of -x-2-10x=25

x = -5

Step-by-step explanation:

start with factoring

-x^2 - 10x - 25 = 0 (i moved 25 to the left side)

then you can multiply the entire equation by -1 to get rid of the negative sign

x^2 + 10x + 25 = 0

now 5x5 = 25 and 5+5 = 10.

so (x^2 + 5x + 5x + 25) = 0

x(x+5) 5(x+5) = 0

(x+5)(x+5) = 0

(x+5)^2 = 0

so x = -5

correct choice is a

step-by-step explanation:
