For the line that has the equation 4x1 + 8x2 = 88, an axis intercept is:

The given equation is

4x + 8x² = 88

That is,

8x² + 4x - 88 = 0

or

2x² + x - 22 = 0

The x-axis intercepts are determined by the solution of the quadratic equation as

x = (1/4) [-1 + / - √ (1+176) ] = 3.076 or - 3.376

Answer: 3.076 or - 3.376
