Question

(x+3)(x+7)=0

Problem answered, solution and why!

Answer 1

the solution set is { - 7, - 3 }

Explanation:

(x + 3)(x + 7) = 0 ← in factored form

equate each factor to zero and solve for x

x + 3 = 0 ( subtract 3 from both sides )

x = - 3

x + 7 = 0 ( subtract 7 from both sides )

x = - 7

solution set is { - 7, - 3 }
