The rule is substract 9
so the answer is b. -44
2x² + 5x + 2 = 9
2x² + 5x + 2 - 9 = 9 - 9
2x² + 5x - 7 = 0
x = <u>-5 +/- √(5² - 4(2)(-7))</u>
2(2)
x = <u>-5 +/- √(25 + 56)</u>
4
x = <u>-5 +/- √(81)
</u> 4<u>
</u>x = <u>-5 +/- 9
</u> 4
x = <u>-5 + 9</u> x = <u>-5 - 9</u>
4 4
x = <u>4</u> x = <u>-14</u>
4 4
x = 1 x = -3.5
