Steps:
Factor 3x^2 + 13x - 10: (3x -2)(x + 5)
(3x -2)(x+5)
= —————
9x^2 - 4
Factor 9x^2 - 4 (3x - 2)(3x-2)

Step-by-step explanation:
<u>Step 1: Define</u>
-1.6 - 2x = 5x + 0.9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 2x on both sides: -1.6 = 7x + 0.9
- Subtract 0.9 on both sides: 2.5 = 7x
- Divide 7 on both sides: 0.357143 = x
- Rewrite: x = 0.357143
