" (xiv) "quad 2((x-1)/(x+3))-7((x+3)/(x-1))=5

Solve each of the following equations: 2((x-1)/(x+3))-7((x+3)/(x-1))=5; x!= -3, 1

Solve the quadratic equation by factorisation: 3((7x+1)/(5x-3))-4((5x-3)/(7x+1))=11 x != 3//5, x != 1//7

3((7x+1)/(5x-3))-4((5x-3)/(7x+1))=11;x!=(3)/(5),-(1)/(7)

If quad f=(x)/(1+x^(2))+(1)/(3)((x)/(1+x^(2)))^(3)+(1)/(5)((x)/(1+x^(2)))^(5)+ and g=x-(2)/(3)x^(3)+(1)/(5)x^(5)+(1)/(7)x^(7)-.... then

Check whether the following are quadratic equations : (1) (x-1)^(2)=2(x-3) (2) x^(2)-2x=(-2)(3-x) (3) (x-2)(x+1)=(x-1)(x+3) (4) (x-3)(2x+1)=x(x+5) (5) (2x-1)(x-3)=(x+5)(x-1) (6) x^(2)+3x+1=(x-2)^(2) (7) (x+2)^(3)=2x(x^(2)-1) (8) x^(3)-4x^(2)-x+1=(x-2)^(3)

((5x+3)-(4x-2))/((5x+3)+(x-1))=(7)/(4)

(x^(2)+5x+7)/(x+1)^(3)=

(2-7x)/(1-5x)=(3+7x)/(4+5x)

(2-7x)/(1-5x)=(3+7x)/(4+5x)
