Answer 1

Answer:

Answer : x = -4 , 3

Step-by-step explanation:

=> 2x^2+2x+6=30

Divide the whole equation by 2

=> x^2 + x -12 = 0

=> x^2 + 4x -3x -12 = 0

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

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

Case (i)

=> x + 4 = 0

=> x = - 4

Case (ii)

=> x - 3 = 0

=> x = 3

Answer : x = -4 , 3
