Question

(x+6)(x-7)(x+8(x+9)=0 Solve the equation

Answer 1

well if the question is

(x +6)(x-7)(x +8)(x+9) = 0

if any binomial factor(s) equal zero then the whole equation will equal zero.

so you need to solve each binomial factor

x + 6 = 0

x -7 = 0

x + 8 = 0

and x + 9 = 0

so there will be 4 unique solutions.
