(x+4)① 12 can be factored as 1×12, 2×6 and 3×4.pq=12,so p and q can be 1 and 12, 2 and 6 or 3 and 4.p+q should be equal to 7, so when p and q are 3 ane 4, p+q=7.Thus, x2+7x+12=(x+3)(x+4).②1×4+1×3=7,thus, x2+7x+12=(x+3)(x+4). ...
We use this equation (from right to left) to factor any trinomial of the form x2 + Bx + C. We find two numbers whose product is C and whose sum is B. Example 1 Factor x2 + 7x + 12. Solution We look for two integers whose product is 12 and whose sum is 7. Consider the ...
