Question

I cant figure this out

Answer 1

x = 2 or x = -1/4

Explanation:

Let's solve your equation step-by-step.

4x2−7x−2=0

For this equation: a=4, b=-7, c=-2

4x^2+−7x+−2=0

Step 1: Use quadratic formula with a=4, b=-7, c=-2.

`x=(-b\pm√(b^2-4ac) )/(2a)`

`x=(-(-7)\pm√((-7)^2-4(4)(-2)) )/(2(4))`

`x=(7\pm√(81) )/(8)`

x = 2 or x = -1/4

Answer:

x = 2 or x = -1/4
