Question

1) Transform the polynomial into a perfect square trinomial to solve.

3x^2+24x=27
a) {-21, -11}
b) {-29,21}
c) {-41,9}
d) {-1,1}

Answer 1

If you would like to solve 3 * x^2 + 24 * x = 27, you can do this using the following steps:

3 * x^2 + 24 * x = 27
3 * x^2 + 24 * x - 27 = 0
3 * (x^2 + 8 * x - 9) = 0
x^2 + 8 * x - 9 = 0
(x + 9) * (x - 1) = 0
1. x = - 9
2. x = 1

None of the above results is correct. The correct result would be {-9, 1}.
