Question

Solve 6x(6x) + 11x - 35 = 0

Answer 1

6x(6x) + 11x - 35 = 0
36x^2 + 11x - 35 = 0
36x^2 + 11x = 35

-11 + or - square root 11^2 - 4 (36) (-35)
divided by
2 * 36

-11 + or - square root 5161
divided by
72

-11 + or - 71.84
divided by
72

There are two answers to the problem:
-11 + 71.84 / 72 = -10 rounded
-11 - 71.84 / 72 = -12. rounded
welcome :/

Answer 2

`36x^2 + 11x - 35=0\\\\ (-b \pm √( b^2 -4( a)(c)) )/(2(a))\\\\ (-11\pm √(11^2 -4(36)(-35)) )/(2(36))\\ \\ (-11\pm √(5161 ) )/(72)\\\\\\ x = 0.8450013919812116\\\\ \text{ } x = -1.1505569475367672`
