The factors of 6x2 are x, 2x, 3x, 6x. The factors of 15 are 1, 3, 5, 15. Eliminate as too large the product of 15 with 2x, 3x, or 6x. Try some reasonable combinations. These would automatically give too large a middle term. ...

x2+ 6x + 9 When we have a monomial factor and two binomial factors, it is easiest to first multiply the binomials. Example 3 Write 3x(x - 2)(x + 3) without parentheses. Solution First, multiply the binomials to obtain 3x(x2+ 3x - 2x - 6) = 3x(x2+ x - 6) ...
The last number at the bottom, which is zero, gives the remainder. Since the remainder is zero, ( x-5 ) is a factor of x4– 6x3– 9x2+ 94x -120. Examples Example 1 Show that ( x-4 ) is a factor of x3-x2-22x +40. ...

x^2:1 6x:1, 2, 3, 6 8:1, 2, 4, 8 If you look at the three lists, there is only one thing that they all share in common, the number one. This means there is no coefficient greater than one to factor out. Then you look at the exponents' powers. 2, 1, and 0. If you...
factor trinomials. For example, in the problem x^2+6x+9, you need to find two numbers that add up to the third term, nine, and two numbers that multiply to the second term, six. The numbers are three and three, as 3 * 3=9 and 3+3=6. The polynomial factors to (x+3)(x+3...
Not all trinomials look like x2+5x+6x2+5x+6, where the coefficient in front of the x2x2 term is 1. In these cases, your first step should be to look for common factors for the three terms.TrinomialFactor out Common FactorFactored 2x2+10x+122x2+10x+12 2(x2+5x+6)2(x2+5x+6...
