Question

how do I solve this equation?
x(x+2)(x-2)(x-5)=y

Answer 1

The roots are where the graph crosses the x axis so set y equal to 0. Then use the property that says "if the product of factors is zero, one of the factors has to be 0" and set each factor equal to 0 and solve each equation.

Answer 2

You should not post answers. Let the asked do the work.

Answer 3

its a collaborative study. i'm learning as well

Answer 4

can you show me ho wmy teacher got the answer \[x ^{4}-5x^{3}-4x^{2}+20x=y\]

Answer 5

and then show me how to do the points because i have the answes, they are x=5,2,-2,0

Answer 6

By multiplying all the factors together.
