x^(2)+5x=14
Step 1: Subtract 14 from both sides.
x^(2)+5x−14=14−14x2+5x−14=0
Step 2: Factor left side of equation.
(x−2)(x+7)=0
Step 3: Set factors equal to 0.
x−2=0 or x+7=0x=2 or x=−7
Answer:
x=2 or x=−7

x^2 - 2x = 7
x^(2)−2x=7
Step 1: Subtract 7 from both sides.
x^(2)−2x−7=7−7x^(2)−2x−7=0
For this equation: a=1, b=-2, c=-7
1x^(2)+−2x+−7=0
Step 2: Use quadratic formula with a=1, b=-2, c=-7.
