using the distributive property, only like exponents can be added or subtracted together. (x^2+3x^2)+(2x+x)+(3+1) or 4x^2+3x+4
Answer:
x = -1 or x = -10
Step-by-step explanation:
x^2 + 11x + 10 = 0
x^2 + 10x + x + 10 = 0
x(x + 10) + 1(x + 10) = 0
(x + 1) (x + 10) = 0
x + 1 = 0 or x + 10 = 0
x = -1 or x = -10
I believe it is b and hmu?
