Solve the equation. Check your solutions when necessary.

2x² − 7x = 4

x= -1/2 = -0.500

x=4

Step-by-step explanation:

2x^2-7x-4=0

2x^2-8x+1x-4=0

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

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

2x+1=0...2x= -1.. x= -1/2         x-4=0 .. x=4

checking the solution

2(-1/2)^2-7(-1/2)=4  4=4

2(4)^2-7(4)=4 4=4

the answer is d. (1.2, -4.7) on edgn

hope this !
