Answer» Answer: 2x2 - 15x) - 4 = 0 STEP 2 : Trying to factor by splitting the middle TERM 2.1 Factoring 2x2-15x-4 The first term is, 2x2 its coefficient is 2 . The middle term is, -15x its coefficient is -15 . The last term, "the constant", is -4 Step-1 : MULTIPLY the coefficient of the first term by the constant 2 • -4 = -8 Step-2 : Find two factors of -8 whose SUM equals the coefficient of the middle term, which is -15 . -8 + 1 = -7 -4 + 2 = -2 -2 + 4 = 2 -1 + 8 = 7 Observation : No two such factors can be found !! |
