Express the following as the product of two bionomials:
xsquared 5x24
Explain please...This is review and i don't remember learning it.... Thanks So Mcuh!!!

1. 2x^2+11x21
This is quadratics. Multiply 2x by x and 7 separatel.Mltiply 3 by x and 7 separately. Add the products and you get a trinomial.
2. (x8)(x+3) If you don't get this, make sure that you understand the chapter on polynomials/quadratics.
