 Multiply Trinomial by binomial in 5 secs ssparikshya Former SMOD 29-06-2012, 10:03 PM (This post was last modified: 29-06-2012, 11:19 PM by ssparikshya.) hi friends, today i gonna show how to multiply binomial by a trinomial in 5 secs Example : (X+2) (X^2 + 3X +2) Step 1: multiply the 1st term of each polynomial to get the 1st term of the answer.. Answer : (X)^3+ ------- + -------- + --------- ; X Multiplied with X^2 Step 2: Multiply the last term of each polynomial to get the last term of the Answer.. Answer: (X)2 + --------- + --------- + 4; 2X2 = 4 Step 3 : Rainbow Multiply the First 2 Terms of each Polynomial to get the first middle term of The Answer Answer: (X)^3 + 5(X)^2 + ---------- + 4 ; 3(x)^2 + 2(x)^2 Step 4 : Rainbow Multiply the Last 2 Terms of each Polynomial to get the Last middle term of The Answer Answer: (X)^3 + 5(X)^2 + 8X + 40 Normal way (X+2) (X^2 + 3X + 2) = X(X^2 + 3X + 2) + 2 ((X)^2 + 3X + 2) = (X)^3 + 3(X)^2 + 2X + 2(X)^2 + 6X + 4 = (X)^3 + 5(X)^2 + 8X + 4 SOURCE : My Experiment Ashok Kumar B.E Civil Engineer 29-06-2012, 10:54 PM Can u post with an Example ? its not clear for me Step 3 & 4 ssparikshya Former SMOD 29-06-2012, 10:54 PM Step 3 : Step 4 : « Next Oldest | « Next Newest
