Find the x-intercept?

Question

y^2=x^3-4x

y=x^2(sqrt25-x^2)

Answer 1

• The first equation

To find x  intercepts substitute y  = 0 in the equation

Apply zero product property.

Apply the formula difference of two squares

Therfore, x  intercepts are 0,2 and -2.

• The second equation is

To find x  intercepts substitute y  = 0 in the equation

Apply zero product property.

Therfore x  intercepts are .
