Question

help solve for x
3x2 + 2x = 7

Answer 1

3x^2 + 2x - 7 = 0
use quadratic formula

Answer 2

3x^2+2x=7

first solve 3x^2
3x^2= 9x so now the equation becomes 9x+2x=7
add 9x+2x
equation becomes 11x=7
divide 11x by 11 to get the x by itself, do the same to 7 (divide by 11)

your answer is x=7/11

Answer 6

huh just now looked at that

Answer 7

3^2 *x = 9x NOT 3x^2

Answer 8

you need to use quadratic formula

x = [-b +- sqrt(b^2 - 4ac)] / 2a

Answer 9

here a = 3, b = 2 and c = -7
