The mistake made by pearl from solving the quadratic equation is that he didn't equate the equation to zero(0) before solving
<h3>How to solve quadratic equation?</h3>
x² - 3x - 10 = 8
x² - 3x - 10 - 8 = 0
x² - 3x - 18 = 0
x² - 6x + 3x - 18 = 0
x (x - 6) + 3(x - 6) = 0
(x + 3) (x - 6) = 0
x + 3 = 0. x - 6 = 0
x = -3. x = 6

Answer:
C. 12
Step-by-step explanation:
Find x by applying the leg rule.
The leg rule is given as:
Hypotenuse/leg = leg/part
Hypotenuse = 24
Leg = 17
Part = x
Plug in the value into the equation:
24/17 = 17/x
Cross multiply
24*x = 17*17
24x = 289
x = 289/24
x = 12.0416667 ≈ 12 (nearest tenth)
