Problem: factor the polynomial x2+9x+20
i need to find the answer to thos qustion ,this question is pre-algebra ,i need to know how to factor ploynomials,what is a polynomial♦

A polynomial is an expression (as given in your statement) with one or more
unknowns (in this case, x), co-efficients (the numbers that multiply the unknowns)
and positive exponents (the 2 in x squared).

Find factors of the constant (20) which add up to the co-efficient of x (9).

x^2 + 9x + 20 = (x + 5) * (x + 4)
