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)

Check whether the following are quadratic equations : (1) (x-3)^(2)=x(2x-5) (2) (2x-3)(8x+1) = (4x+5)(4x-5) (3) (5x+3)(x-2)=(4x+3)(2x-1) (4) (2x+5)^(3)=8(x-1)^(3) (5) x^(2)+7x-8=x(x+5) (6) x^(3)+9x^(2)-7x+2=(x+3)^(3)

Solve each of the following equation and check your answers: (i) 6(1-4x)+7(2+5x)=53 (ii) 5(2-3x)-17(2x-5)=16

(12x + 17) / (3x + 1)-(2x + 15) / (x + 7) = 3 (1) / (5), x! =-(1) / (3), -7

Solve: 6(1-4x)+7(2+5x)=53 . Check the result.

1/(x^2-3x+2)+1/(x^2-5x+6)+1/(x^2-4x+3)

x+7-(8x)/(3)=(17)/(6)-(5x)/(2)

Solve each of the following equation and check your answers: 6(1-4x)+7(2+5x)=535(2-3x)-17(2x-5)=16

(x-1)/(x-2)-(x-2)/(x-3)=(x-5)/(x-6)-(x-6)/(x-7)
