215 - 44.49 (I added the two deductions mentally) = 170.51

So we want 6% of 215 or .06 x 215 = $12.90
$170.51 - 12.90 = $157.61 net income.

Step-by-step explanation:
2x² - 7x - 3 = 1
Step 1: 2x² - 7x - 4 = 0
Step 2: incorrect.
Use Quadratic Formula to solve for roots.
x = [7 ± √(7² – 4·2(-4))] / [2·2]
= [7 ± √81] / 4
= [7 ± 9] /4
= -0.5, 4
