The value of the determinant |[x, x+y, x+2y], [x+2y, x,x+y],[x+y, x+2y, x]| is (a) 9x^2(x+y) (b) 9y^2(x+y) (c) 3y^2(x+y) (d) 7x^2(x+y)

Simplify : (x + y)(2x + y) + (x + 2y)(x – y)

Simplify. (x + y)(2x + y) + (x + 2y)(x-y)

Simplify : ( 3y ( x - y) - 2x ( y -2x))/( 7x ( x - y) - 3 ( x ^(2) - y ^(2)))
