Answer:
Step-by-step explanation:
2.1 Factoring 9y2+30y-14
The first term is, 9y2 its coefficient is 9 .
The middle term is, +30y its coefficient is 30 .
The last term, "the constant", is -14
Step-1 : Multiply the coefficient of the first term by the constant 9 • -14 = -126
Step-2 : Find two factors of -126 whose sum equals the coefficient of the middle term, which is 30 .
-126 + 1 = -125
-63 + 2 = -61
-42 + 3 = -39
-21 + 6 = -15
-18 + 7 = -11
-14 + 9 = -5
-9 + 14 = 5
-7 + 18 = 11
-6 + 21 = 15
-3 + 42 = 39
-2 + 63 = 61
-1 + 126 = 125
