Rewrite the equation y=x2−16 in factored form and find the zeros of the equation.

Question

Rewrite the equation y=x^2−16 in factored form and find the zeros of the equation. Then use the zeros to find the line of symmetry of the parabola represented by the equation.

What is the equation for the line of symmetry of the parabola represented by the equation y=x^2−16?

Enter your answer as the correct equation, like this: x = 42

Answer 1

y=(x+4)(x-4) and the axis is x=0
