Question

Find the solution to the equation below. 2x^2+3x-20=0

A. x= -4, -3/2

B. x= -4, 3/2

C. x= -5/2, 4

D. x= -4, 5/2

Answer 1

C maybe bro I’m not really sure tho think I’m messing up

Answer 2

The right choice is (D) x= -4, 5/2

Explanation:

2x^2+3x-20=0

By factoring the expression we get

2x²2 +8x−5x−20=0

(x+4) (2x−5) = 0

Now

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

and

(2x-5) = 0 OR x = 5/2

S the solutions are

x= -4 and x = 5/2
