    Trying to factor by splitting the middle term 2.1 Factoring 6x2+x-35 The first term is, 6x2 its coefficient is 6 . The middle term is, +x its coefficient is 1 . The last term, "the constant", is -35 Step-1 : Multiply the coefficient of the first term by the constant 6 • -35 = -210 Step-2 : Find two factors of -210 whose sum equals the coefficient of the middle term, which is 1 . -210 + 1 = -209 -105 + 2 = -103 -70 + 3 = -67 -42 + 5 = -37 -35 + 6 = -29 -30 + 7 = -23 -21 + 10 = -11 -15 + 14 = -1 -14 + 15 = 1 That's it Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 15 6x2 - 14x + 15x - 35 Step-4 : Add up the first 2 terms, pulling out like factors : 2x • (3x-7) Add up the last 2 terms, pulling out common factors : 5 • (3x-7) Step-5 : Add up the four terms of step 4 : (2x+5) • (3x-7) Which is the desired factorization Final result : (3x - 7) • (2x + 5)
