Factorize z-7 +7xy - xyz

Factorize 1+x+y-z+xy-yz-zx-xyz

Solve xy(7+8x)

Multiply: (7xy+5y) by 3xy

Let A=3x^(2)-7xy+6 and B= 7xy-5x^(2)+15 Find. (I) A+B " " (II) 2A+B

Solve (9xy + 7 xy + 9x ^(2)) + ( 8 + x ^(2) - xy - y ^(2) + 1).

Add: (i) 3x, 7x (ii) 7y, -9y (iii) 2xy, 5xy, -xy (iv) 3x, 2y (v) 2x^(2), -3x^(2), 7x^(2) (vi) 7xyz, -5xyz, 9xyz, - 8xyz (vii) 6a^(3) , - 4a^(3), 10 a^(3), - 8a^(3) (viii) x^(2) - a^(2), -5x^(2) + 2a^(2), -4x^(2) + 4a^(2)

Subtract: -8xy from 7xy
