What is the standard form of y= (x+2) (2x+5) ? Algebra Polynomials and Factoring Polynomials in Standard Form 1 Answer Rachel Feb 25, 2016 y=2x^2+9x+10 Explanation: We begin with (x+2)(2x+5). To simplify this, we just need to multiply out the two parentheses. That gives us 2x^2+5x+4x+10. If we combine like-terms, we have 2x^2+9x+10. That's it; we're done!
