Solve the quadratic equation (2x+3)(x-3)=7. If there is more than one correct answer, enter your answers as comma separated list. If there are no real solutions,enter none. Please help!!!!! :(

Answer 1

It is good to have the quadratic in factored form but useful only if the product is zero.
In your case it is 7, so that is useless.

Expand and recalculate the constant ....
2x^2 - 6x + 3x - 9 = 7
2x^2 - 3x - 16 =0

hint: it does not factor , so you have to use the quadratic formula
