Isolate the variable by dividing each side by factors that don't contain the variable. p=q/2r
Answer:
2
Step-by-step explanation:
x2+3x=6
Step 1: Subtract 6 from both sides.
x2+3x−6=6−6
x2+3x−6=0
For this equation: a=1, b=3, c=-6
1x2+3x+−6=0
Step 2: Use quadratic formula with a=1, b=3, c=-6.
x=
−b±√b2−4ac
