y=x^(2)-(a+b)x+ab

Solve for x and y:x^(2)-y^(2)=xy-ab,(x+y)(ax+by)=2ab(a+b)

If a,b, x in R, a lt b and y =(x^(2) -ab)/(2x-a -b), then-

Solve :a(x+y)+b(x-y)=a^(2)-ab+b^(2)a(x+y)-b(x-y)=a^(2)+ab+b^(2)

Solve the following simultaneous linear equations in two variables by the method of cross-multiplication : a(x+y)+b(x-y)=a^(2)-ab+b^(2) a(x+y)-b(x-y)=a^(2)+ab+b^(2)

Solve: (a - b )x + (a + b)y = a^(2) - 2ab - b^(2) and (a + b) (x + y) = a^(2) + b^(2)

Solve for x and y. (a-b)x+(a+b)y=a^(2)-2ab-b^(2) , (a+b)(x+y)=a^(2)+b^(2)

(a-b)x+(a+b)y=a^(2)-2ab-b^(2)(a+b)(x+y)=a^(2)+b^(2) find x and y

The lines (a+b)x+(a-b)y=2ab, (a-b)x +(a+b)y=2ab , and x+y=0 form an isosceles triangles whose vertical angle is
