Answer» Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)PROOF : (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2Note : AB = BA is the commutative property of multiplication.Note : - AB + AB equals zero and is therefore ELIMINATED from the expression.Check : x2 is the square of x1 Check : a1 is not a square !!Ruling : Binomial can not be factored as the difference of two perfect squaresFinal result :FINAL result : x2 - ay2Hope it helps u(◍•ᴗ•◍)❤ |
