Question

How do you use the quadratic formula to solve `-2x^2+3x+4=1`?

Answer 1

`color(gray)(x = (3 - sqrt33) / 4, (3 + sqrt33) / 3`

Explanation:

`-2x^2 + 3x + 4 - 1 = 0`

`-2x^2 + 3x + 3 = 0`

`a = -2, b = 3, c = 3`

`"Quadratic formula is " x = (-b +- sqrt(b^2 - 4ac)) / (2a)`

`x = (-3 +- sqrt(9 + 24)) / -4`

`color(gray)(x = (3 - sqrt33) / 4, (3 + sqrt33) / 3`
