निम्न बहुपदों के गुणनखण्ड कीजिए - `7(x+y)^(3)+14(x+y)^(2)+28(x+y)`

Factorise the following polynomials : (i) x^(3)+x^(2) " " (ii) a^(3)bc+ab^(3)c-abc^(3) " " (iii)ab(x+y)+bx(x+y) (iv) 32(x+y)^(2)+2(x+y) " " (v) x(x-y)-z(y-x) " " (vi) (1-x)-(x-1)x (vii) 7(x+y)^(3)+14(x+y)^(2)+28(x+y)

Factorise the following polynomials : (i) x^(3)+x^(2) " " (ii) a^(3)bc+ab^(3)c-abc^(3) " " (iii)ab(x+y)+bx(x+y) (iv) 32(x+y)^(2)+2(x+y) " " (v) x(x-y)-z(y-x) " " (vi) (1-x)-(x-1)x (vii) 7(x+y)^(3)+14(x+y)^(2)+28(x+y)

Simplify: (3x+2y)(4x+3y)-(2x-y)(7x-3y)

Factorise (2x- y)^(2) - 14 x + 7 y - 18

Simplify: (2x+3y)(3x4y)-(7x+3y)(x+2y)

Simplify: (2x + 5y)(3x + 4y) - (7x + 3y)(2x + y)

7 (y + 3) -2 (x + 2) = 14.4 (y-2) +3 (x-3) = 2

Find the value of X and Y (X और Y का मान ज्ञात कीजिए) I. x^(2)-14x+48=0 II. y^(2)+6=5y

(14)/(x+y)+(3)/(x-y)=5,(21)/(x+y)-(2)/(x-y)=1

Simplify: (2x+3y)(3x+4y)-(7x+3y)(x+2y)
