[tex]\bf 2x^2+10x+12\implies 2(x^2+5x+6)\implies 2(x+3)(x+2)[/tex]
recall that 3 * 2 = 6, and 3x + 2x = 5x.
Answer:
Step-by-step explanation:
It is a little easier if you take out the two.
2*(x^2 + 5x +6)
The numbers that multiply to 6 and adds to 5 are 3 and 2
2*(x + 3)(x + 2)
So that's how the trinomial factors.
