A 2 b 2 c 2 ab bc ca = 0 multiplying by 2 on both sides 2a 2 2b 2 2c 2 2ab 2bc 2ac = 0 a 2 a 2 b 2 b 2 c 2 c 2 2ab 2bc 2ac = 0 (a 2 b 22ab) (b 2 c 22bc) (a 2 c 22ac) = 0 (ab) 2 (bc) 2 (ac) 2 = 0 but, sum of positive quantities can be zero if and only if each quantity in that expression is zero so, (ab) 2 = 0, ab = 0 , a= b (bc) 2 = 0. See the proof below If abc=0 Then, a=bc=(bc) Therefore, a^2bc=((bc))^2bc=(bc)^2bc =b^2c^22bcbc =b^2c^2bc b^2ca=b^2c((bc))=b^2c^2bc c^2ab=c^2.

If abc=0, then c=ba Substitute c=ba into the 'prove' equation for c and simplify it You should get, a^2abb^2=a^2abb^2 or 1 = 1, which is true. For any three positive numbers a, b, and c such that a 2 b 2 = c 2, there exists a triangle with sides a, b and c, and every such triangle has a right angle between the sides of lengths a and b An alternative statement is For any triangle with sides a, b, c, if a 2 b 2 = c 2, then the angle between a and b measures 90°. Then (a b c) 2 = (a x) 2 = a 2 2ax x 2 = a 2 2a (b c) (b c) 2 Therefore, (a b c) 2 = a 2 b 2 c 2 – 2ab 2bc – 2ca Workedout examples on square of a trinomial 1 Expand each of the following (i) (2x 3y 5z) 2 Solution (2x 3y 5z) 2.

Equivalently, f(ab) = ab(a−2 b2) a2 b2 (3) We know however (see (1)) that f(ab) must be either ab or 1/ab If f(ab) = ab then by (3) a−2 b2 = a2 b2, so that a = 1 But, as f(1) = 1, this contradicts the relation f(a) 6= a Likewise, if f(ab) = 1/ab then (3) gives a2b2(a−2 b2) = a2 b2, whence b = 1. See the proof below If abc=0 Then, a=bc=(bc) Therefore, a^2bc=((bc))^2bc=(bc)^2bc =b^2c^22bcbc =b^2c^2bc b^2ca=b^2c((bc))=b^2c^2bc c^2ab=c^2.

If A is invertible and AB=AC then B=C This is true because if A is invertible,婦ou multiply both sides of the equation AB=AC from the left by A inverse to get IB=IC which simplifies to B=C since膝 is the identity matrix. If, as is normal, ab represents a times b, etc then ab ab cc = 2ab c2 which is generally not the same as abc.
