WebThen note x−y = a2 −bc + ca− b2 = (a −b)(a+ b+ c) = 0y −z = b2 − ca+ ab −c2 = (b− c)(a +b +c) = 0 Thus we have x = y = z. We are done. If a, b and c are sides of a triangle, then prove that a2(b +c −a)+b2(c+ a− b)+c2(a + b −c) ⩽ 3abc. It's true for all non-negatives a , b and c . Indeed, since our inequality is symmetric ... WebSolution. ab (a 2 + b 2 - c 2) - bc (c 2 - a 2 - b 2) + ca (a 2 + b 2 - c 2) = ab (a 2 + b 2 - c 2) + bc (a 2 + b 2 - c 2) + ca (a 2 + b 2 - c 2) = (a 2 + b 2 - c 2 ) [ab + bc + ca] Concept: Factorisation by Taking Out Common Factors.
