Question

What are the solutions of 8x2 = 6 + 22x? Check all of the boxes that apply.

Answer 1

x is equal to 3 and -0.25

Explanation:

The answer can be found by factoring the equation and solving for zero:

`8x^2 = 6 + 22x\\4x^2 = 3 + 11x\\4x^2 - 11x - 3 = 0\\4x^2 -12x + x - 3 = 0\\4x(x - 3) + (x - 3) = 0\\(4x + 1)(x - 3) = 0`

So x is equal 3 and -0.25
