Evaluate
3x2×3x
Multiply the terms
9x2×x
Multiply the terms with the same base by adding their exponents
9x2+1
Add the numbers
9x3
9x3−90=0
Move the constant to the right-hand side and change its sign
9x3=0+90
Removing 0 doesn't change the value,so remove it from the expression
9x3=90
Divide both sides
99x3=990
Divide the numbers
x3=990
