Quadratic 6X2 + 5X = -7

poizon [28]

Ok, so here your being asked to solve 6x2 + 5x = -7

The procedure that I did was using this formula it led me to get the following:
Using the formula:

x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6)
x = 5 ± √ 25 + 144 / 12
x = 5 ± √ 169 / 12
x = 5 ± 13/12

x1 = 5 + 13/12
x1 = 18/12
x1 = 3/2

x2 = 5 - 13/12
x2 = -8/12
 x2 = - 2/3

Hope this helped :)
