The first term is, x2 its coefficient is 1 . The middle term is, -7x its coefficient is -7 . The last term, "the constant", is +10. Step-1 : Multiply the coefficient of the first term by the constant 1 • 10 = 10. Step-2 : Find two factors of 10 whose sum equals the coefficient of the middle term, which is -7 .
