Learn how to factor a trinomial of the form ax2 + bx + c when a is not equal to 1 by getting rid of the "impostor". The impostor here is the leading coefficient a or the coefficient of ax2. In order to use this method, GCF(a,b,c) = 1 (The greatest common factor of a, ...
3x^3 + 8x^2 - 9x + 2 is an example. You can't use grouping to factor out a GCF in a way that would produce a common factor. In order to explain how this works, you need to know that when solving an equation by factoring, you need to set the factored out thing equal to 0 ...
Factorx2+5x+4x2+5x+4 Step 1 Identify a, b and c in the trinomial ax2+ bx + c a=1b=5c=4a=1b=5c=4 Step 2 Write down all factors ofccwhich multiply to44 (Note: since44ispositivewe only need to think about pairs that are either bothpositiveorboth negative. Remember a negative ...
