Answer» ng 7M2-5m-6 The first term is, 7m2 its COEFFICIENT is 7 . The middle term is, -5m its coefficient is -5 . The last term, "the constant", is -6 Step-1 : Multiply the coefficient of the first term by the constant 7 • -6 = -42 Step-2 : Find TWO factors of -42 whose sum equals the coefficient of the middle term, which is -5 . -42 + 1 = -41 -21 + 2 = -19 -14 + 3 = -11 -7 + 6 = -1 -6 + 7 = 1 -3 + 14 = 11 -2 + 21 = 19 -1 + 42 = 41 Observation : No two such factors can be found !!answer = 7m2 - 5m - 6 |
