## Factor completely

I am to factor this completely and I am stuck. 2r^3 + 8r^2 +6r Note: x^2 is x-squared (that is, x with the superscript 2), etc. 2 is a factor and r is a factor so the equation becomes 2r(r^2 + 4r + 3) then we can factor the term in parentheses. To do that,

## Just can't get it.

Factor completely or state that this is prime (cannot be factored) 2y^4 + 28y^3 + 98y^2 Note: x^2 is x-squared (that is, x with the superscript 2), etc. 2y^4 + 28y^3 + 98y^2 = 2 y^2 (y^2 + 14 y + 49) The last expression (in parentheses) is a perfect
