What is the value of 6x-3x +7 if x=9?

1 answer:

8 0

$6x - 3x + 7 \\ 3x + 7 \\ 3(9) + 7 \\ 27 + 7 \\ = 34$
Combine like terms and "plug in" x into the equation to eventually get 34 after some addition

Answer:

x^2+5x-6

a = 1 b = 5 and c = -6

Using the quadratic formula:

x = [-5 +- sq root (25 -4 * 1 *-6) ] / 2 * 1

x = [-5 +- sq root (49)] / 2

x = [-5 +- 7] / 2

x1 = 1

x2 = -6
