Factor: ( x 5 32 ) Factor: 2x^{2} - 11x - 21 Factor: x^2 - 9. Factor: 4x^3 - 32 Factor: 3x^3 + 9x^2 - 3x - 9. Factor 4x^2 - x. Factor completely. 125y^3 - 8x^6 Factor Completely: x^2 - 12x + 20. Factor x2 + x - 72. a) (x+8)(x-9) b) (x-8)...
x2 + 8x + 16 factored is (x + 4)(x + 4). In general, if we have a quadratic expression that is factorable and is of the form x2 + bx + c, then we can...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our ...
Multiply (x - y)(a + 2) and see if you get the original expression. Again, multiply as a check. Sometimes the terms must first be rearranged before factoring by grouping can be accomplished. Example 7 Factor 3ax + 2y + 3ay + 2x. Solution The first two terms have no common factor...

We see that the only pair of factors whose product is 12 and whose sum is 7 is 3 and 4. Thus, x2+ 7x + 12 = (x + 3)(x + 4) Note that when all terms of a trinomial are positive, we need only consider pairs of positive factors because we are looking for a pair of factors...
11use the factor therem to factorise the following cubics as far as possible:f(x)=x(的三次方)-7x+62find a given that (x+4) is a factor of f(x)=x(的三次方)+8x^+ax+12 and hence factorise f(x) completely.3show that (x-2) is a factor of f(x)=x的三次方-4x^+x+6 and ...
