What are the solutions to the quadratic equation 3(x − 4)2 = 75?
2 answers:
If you would like to know the solutions to the quadratic equation, you can find this using the following steps:
3 * (x - 4)^2 = 75
3 * (x^2 - 8x + 16) = 75 /3
<span>x^2 - 8x + 16 = 25
</span>x^2 - 8x + 16 - 25 = 0
x^2 - 8x - 9 = 0
(x - 9) * (x + 1) = 0
1. x = 9
2. x = -1
The correct result would be <span>x = −1 and x = 9.</span>
