Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

Subtract : (3)/(2)x^(2)y+(4)/(5)y-(1)/(3)x^(2)yz from (12)/(5)x^(2)yz-(3)/(5)xyz+(2)/(3)x^(2)y

(x^(4))/(4)+(y^(3))/(3)-(3z^(2))/(5)+(x^(4))/(3)-(3y^(3))/(5)+(z^(2))/(4)-(3x^(4))/(5)+(y^(3))/(4)+(z^(2))/(3)

"((2x)/5-(3y)/4)((2x)/5+(3y)/4)

(x^(4))/(4) + (y^(3))/(3) - (3z^(2))/(5) + (x^(4))/(3) - (3y^(3))/(5) + (z^(2))/(4) - (3x^(4))/(5) + (y^(3))/(4) + (z^(2))/(3) = "________" .

Solve for x and y : (y+7)/(5)=(2y-x)/(4)+3x-5 (7-5x)/(2)+(3-4y)/(6)=5y-18

Solve : {:((34)/(3x+4y)+(15)/(3x-2y)=5),((25)/(3x-2y)-(8.50)/(3x+4y)=4.5):}
