Step-by-step explanation:
6x^2 + 7x - 10 = 0
6x^2 + 12x - 5x - 10 = 0
6x ( x + 2 ) - 5 ( x + 2) = 0
(6x - 5 ) ( x + 2 ) = 0
6x - 5 = 0 | x + 2 = 0
6x = 5 | x = - 2
x = 5/ 6 | x = -2
x = 5 / 6 because minus roots are not it's answer

Answer:
Step-by-step explanation:
Let p ( x ) = 6x² + 7x - 10 = 0
⇒ 6x² + 12x - 5x - 10 = 0
⇒6x ( x + 2 ) - 5 ( x + 2 ) = 0
⇒ ( 6x - 5 ) ( x + 2 ) = 0
⇒ x = 5/6 or - 2
