Math Problem Statement

(x+y)2−(xy)−2=0 simple it like(x+y+1)(x+y-2)

Solution

We start with the given equation:

(x+y)2(xy)2=0(x + y)^2 - (x - y) - 2 = 0

Step 1: Expand the Square

Expanding (x+y)2(x + y)^2:

x2+2xy+y2x^2 + 2xy + y^2

Thus, the equation becomes:

x2+2xy+y2(xy)2=0x^2 + 2xy + y^2 - (x - y) - 2 = 0

Step 2: Rearrange the Terms

Rewriting the equation:

x2+y2+2xyx+y2=0x^2 + y^2 + 2xy - x + y - 2 = 0

We now seek to factorize it.

Step 3: Try Factoring

We attempt factoring by considering expressions that multiply to x2+y2+2xyx+y2x^2 + y^2 + 2xy - x + y - 2. Checking for a binomial factorization of the form (x+y+a)(x+y+b)(x + y + a)(x + y + b), we set:

(x+y+a)(x+y+b)=x2+2xy+y2+(a+b)(x+y)+ab(x + y + a)(x + y + b) = x^2 + 2xy + y^2 + (a + b)(x + y) + ab

Matching with x2+2xy+y2x+y2x^2 + 2xy + y^2 - x + y - 2, we get:

a+b=1,ab=2a + b = -1, \quad ab = -2

Solving for aa and bb, the possible values are a=2,b=1a = -2, b = 1, so the factorization is:

(x+y2)(x+y+1)=0(x + y - 2)(x + y + 1) = 0

Final Answer:

(x+y+1)(x+y2)=0(x + y + 1)(x + y - 2) = 0
