middle term of factor 4u ^ 2 - 45x + 9u = 0
Answers
Step-by-step explanation:
Factoring 44x2-45x-56
The first term is, 44x2 its coefficient is 44 .
The middle term is, -45x its coefficient is -45 .
The last term, "the constant", is -56
Step-1 : Multiply the coefficient of the first term by the constant 44 • -56 = -2464
Step-2 : Find two factors of -2464 whose sum equals the coefficient of the middle term, which is -45 .
-2464 + 1 = -2463
-1232 + 2 = -1230
-616 + 4 = -612
-352 + 7 = -345
-308 + 8 = -300
-224 + 11 = -213
-176 + 14 = -162
-154 + 16 = -138
-112 + 22 = -90
-88 + 28 = -60
-77 + 32 = -45 That's it
