Let's verify if `y = frac(5)(4)` then `-(-y) = y`

Let's apply, (a+b)^2 +( a-b)^2 = 2(a^2 + b^2) or (a+b)^2-(a -b)^2 =4ab or ab = (frac(a+b)(2))^2 - (frac(a-b)(2))^2 to find the following. Let's find frac(x^2 + y^2)(2xy) when (x + y) = 9 and ( x - y) = 5

Let's verify: (4)xx(-5)xx7 +8 =10

Let's write the value of x^3 + y^3 by calculations if x + y = 2 and frac(1)(x) + frac(1)(y) = 2

Let's simplify : 10frac(3)(10) xx 6frac(4)(3) xx frac(4)(11)

Let's solve : frac(x)(4) - frac(x)(2) = 3frac(1)(2) - frac(x)(3)

Let's simplify : frac(9)(10) div frac(3)(8) xx frac(2)(5)

Let's simplify: frac(x)(x^2 + xy) - frac(x)(x-y)

Solve:- frac(y)(3) = frac(2)(9)

Let's solve : frac(1)(3)(x-2) + frac(1)(4) (x + 3) = frac(1)(5)(x + 4) + 15

Let's Multiply : (frac(x)(y) - frac(y)(3)) (frac(2x)3) - frac(3y)(5)
