The value of ac in this quadratic equation (3x - 8)(x + 5) is -120.
What is a quadratic equation?In Mathematics, the standard form of a quadratic equation is given by the following mathematical expression:
ax² + bx + c = 0 ......equation 1.
Therefore, we would expand the bracket as follows:
(3x - 8)(x + 5) = 0
3x² + 15x - 8x - 40 = 0
3x² + 17x - 40 = 0 .....equation 2.
By comparing equation 1 and equation 2, we have the following parameters:
a = 3
b = 17
c = -40
For the value of ac, we have:
ac = 3 × (-40)
ac = -120.
