Question

What is



4x2 + 2x - 7 = 0

Answer 1

x =
`(-1)/(4) + (1)/(4) √(29)`

Explanation:

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

4x²+2x+−7=0

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

x=
`\frac{-b + \sqrt{bx^(2)-4ac } }{2a}`

x = −(2)±√(2)2−4(4)(−7) ÷ 2(4)

x = −2±√116 ÷ 8

x =
`(-1)/(4) + (1)/(4) √(29)`
