Best ResponseYou've already chosen the best response.0look at the first and last terms in each bracket add the first pair that will give you the first term in the answer add the last pair  that will give you the last term in the answer there is only one answer that works @Janu16 the poster cannot know if you are right if you just post the answer @sistrunk23 I suggest you check the answer  it is quite likely wrong

Best ResponseYou've already chosen the best response.1Step 1 : Raise x to the 2nd power Exponentiation : Equation at the end of step 1 : (((4•(x2))2x)+5)+(((2•x2)2x)8) Step 2 : Raise x to the 2nd power Exponentiation : Equation at the end of step 2 : (((4 • x2)  2x) + 5) + (2x2  2x  8) Step 3 : Simplify 4x22x+5 + 2x22x8 Trying to factor by splitting the middle term 3.1 Factoring 6x24x3 The first term is, 6x2 its coefficient is 6 . The middle term is, 4x its coefficient is 4 . The last term, "the constant", is 3 Step1 : Multiply the coefficient of the first term by the constant 6 • 3 = 18 Step2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is 4 . 18 + 1 = 17 9 + 2 = 7 6 + 3 = 3 3 + 6 = 3 2 + 9 = 7 1 + 18 = 17 Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored Final result : 6x2  4x  3
