Remember to look first for a GCF and to check by multiplying. 1. x2+4x+4 2. x2-20x+100 3. 64+16x+x2 4. 9x2 - 42x + 49 5. 36x2+96xy+64y2 Found 2 solutions by Alan3354, stanbon:Answer by Alan3354(34677)   (Show Source): You can put this solution on YOUR website!Factor completely. Remember to look first for a GCF and to check by multiplying. 1. x2+4x+4 Both ends, the x^2 & the 4, are squares. Try that first. 2. x2-20x+100 Same comment 3. 64+16x+x2 Same comment 4. 9x2 - 42x + 49 Same comment 5. 36x2+96xy+64y2 Factor out 4 first, then same comment Answer by stanbon(60772)   (Show Source): You can put this solution on YOUR website!1. x2+4x+4 = (x+2)^2 --------------------------- 2. x2-20x+100 = (x-10)^2 --------------------------- 3. 64+16x+x^2 = (8+x)^2 --------------------------- 4. 9x2 - 42x + 49 = (3x-7)^2 --------------------------- 5. 36x2+96xy+64y2 = (6+8y)^2 =============================== Cheers, Stan H. ===============================
