Evaluate

2 x^{2} \times 8 x = x^{2} - 16

Multiply

More Steps

16 x^{3} = x^{2} - 16

Move the expression to the left side

16 x^{3} - (x^{2} - 16) = 0

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

16 x^{3} - x^{2} + 16 = 0
