Solve for x. write both solutions, separated by a comma

2x^2-7x-4=0

2x^2-7x-4=0

2x^2-8x+x-4=0

2x (x-4) + 1 (x-4) = 0

(2x+1) (x-4) = 0

x=-1/2, 4

Hi again

2x² - 7x - 4 = 0

Again, all you have to do is factor left side

(2x + 1) (x - 4) = 0

Set factors equal to 0

2x + 1 = 0 or x - 4 = 0

2x = 0 - 1 or x = 0 + 4

2x = - 1 0r x = 4

x = - 1/2 or x = 4

Answer : (-1/2, 4)
