Answer:
x=√3
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2+3x−2=3x+7
Step 1: Subtract 3x from both sides.
3x2+3x−2−3x=3x+7−3x
3x2−2=7
Step 2: Add 2 to both sides.
3x2−2+2=7+2
3x2=9
Step 3: Divide both sides by 3.
3x2
3
=
9
3
x2=3
Step 4: Take square root.
x=±√3
x=√3 or x=−√3
