Answer 4

It's much easier to tackle this problem backwards.

Remember how you solved for the roots of an equation by factoring. For example:
\[x^{2}-x-2\]
Factors into (x+1)(x-2)
Setting x+1=0 and x-2=0, you would get x= {-1, 2}, right?

So you know if the roots are -1 and 2, multiplying (x+1)(x-2) would give you the equation.

Do the same for your problem. What three expressions multiplied would give you 4, -5, and 7 as the roots?

Answer 5

multiply \[(x-4)(x-7)(x+5)\] to get your answer
