Expand (x 2y z) 2 Solution (x 2y z) 2 is in the form of (a b c) 2 Comparing (a b c) 2 and (x 2y z) 2, we get a = x b = 2y c = z Write the formula / expansion for (a b c) 2 (a b c) 2 = a 2 b 2 c 2 2ab 2bc 2ac Substitute x for a, 2y for b and z for c (x 2y z) 2First remove a common factor Then factor the difference of two squares e) 32 m2n − 50 n3 = 2n(16m2 − 25n2) = 2n(4m 5n) (4m − 5n) The entire figure on the left is a square on side a The square b2 has been inserted in the upper left corner, so that the shaded area is the difference of the two squares, a2 − b2Steps for Solving Linear Equation y = 3x 4 y = 3 x 4 Swap sides so that all variable terms are on the left hand side Swap sides so that all variable terms are on the left hand side 3x4=y 3 x 4 = y Subtract 4 from both sides Subtract 4 from both sides
May 29, 18Transcript Example Expand (4a – 2b – 3c)2 (4a – 2b – 3c)2 = (4a (–2b) (–3c)) 2 Using (x y z)2 = x2 y2 z2 2xy 2yz 2zx Putting x = 4aAnd now solve the difference of two squares with a = 36 and b = 4y 2 Solution Factor the equation (rearranged) 36 − 4 y 2 using the identity a 2 − b 2 = ( a b) ( a − b) First factor out the GCF 4 ( 9 − y 2) Both terms are perfect squares so from a 2 b 2 we can find a and bMultiply as we do multiplication of two binomials and we get = a (a b) b (a b) = a 2 ab ab b 2 Add like terms and we get = a 2 2ab b 2 Rearrange the terms and we get = a 2 b 2 2ab Hence, in this way we obtain the identity ie (a b) 2 = a 2 b 2 2ab Following are few applications this identity
