Answer: x=−3 or x=13
Step-by-step explanation:
Step 1: Subtract 39 from both sides.
x2−10x−39=39−39
x2−10x−39=0
Step 2: Factor left side of equation.
(x+3)(x−13)=0
Step 3: Set factors equal to 0.
x+3=0 or x−13=0
x=−3 or x=13
First you put 2.13 on top of a fraction and 36 on the bottom. Then you divide 36 by 2.13 and put the answer, 16.90, on top of another fraction and put a 1 on the bottom of that other fraction.
