ok this took a while But ...The first term is, x2 its coefficient is 1 .
The middle term is, +2x its coefficient is 2 .
The last term, "the constant", is +148
Step-1 : Multiply the coefficient of the first term by the constant 1 • 148 = 148
Step-2 : Find two factors of 148 whose sum equals the coefficient of the middle term, which is 2 .
pls let me be right
