Answer:
The answer is -28
Step-by-step explanation:
The first term is, y2 its coefficient is 1 .
The middle term is, -28y its coefficient is -28 .
The last term, "the constant", is +196
Step-1 : Multiply the coefficient of the first term by the constant 1 • 196 = 196
Step-2 : Find two factors of 196 whose sum equals the coefficient of the middle term, which is -28 .
-196 + -1 = -197
-98 + -2 = -100
-49 + -4 = -53
-28 + -7 = -35
-14 + -14 = -28
