Question

solve the quadratic equation 3x^2-5x-12=0​

Answer 1

Answer:

x = 3    ;    x = -4/3

Step-by-step explanation:

3x² - 5x - 12 = 0​

Using splitting the middle term,

3x² - 9x + 4x - 12 = 0

3x(x - 3) + 4(x - 3) = 0

(x - 3)(3x +4) = 0

x - 3 = 0          ;         3x + 4 = 0

x = 3                         3x = -4

                                x = -4/3
