Answer:
The first term is, 3x2 its coefficient is 3 .
The middle term is, +22x its coefficient is 22 .
The last term, "the constant", is +40
Step-1 : Multiply the coefficient of the first term by the constant 3 • 40 = 120
Step-2 : Find two factors of 120 whose sum equals the coefficient of the middle term, which is 22 .
