Question

solve the factored quadratic equation (19x - 3)(9 + x) = 0
the solution set is x = {-9, 3/19}
the solution set is x = {19/3, 9}
the solution set is x = {-9, 10/3}
the solution set is x = {-9, 3}

Answer 1

Set each factor equal to zero (zero-product property):

19x − 3 = 0 ⇒ x = 3/19
9 + x = 0 ⇒ x = −9

So the solution set is x = {−9, 3/19}.
