Question

Find the value or values of x in the quadratic equation x2 = 6x 9.

a. x = 0, x = 1
b. x = 9
c. x = 3
d. x = 3, x = 2 User: Which of the following is the greatest common factor of the terms 48s5t3u2 and 40s3tu4?

Answer 1

x2 = 6x-9
x2 - 6x + 9 = 0
(x-3)(x-3) = 0
x = 3

So the value of x is 3. The correct answer is letter c.

The greatest common factor is: 8s3tu2
