Solve by factoring: x² - 15 = 2x ( rewrite it in standard form)

x=−3 or x=5

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−15=2x

Step 1: Subtract 2x from both sides.

x2−15−2x=2x−2x

x2−2x−15=0

Step 2: Factor left side of equation.

(x+3)(x−5)=0

Step 3: Set factors equal to 0.

x+3=0 or x−5=0

x=−3 or x=5

p = 6s
