Solve : (i) -2 le ||x^(2) +1| -3 | le 7 (ii) |x^(2) - 4x| le 5

Solve: x/2+x/3-x/4=7

Solve: (3x+5)/(2x+7)=4

Solve: (x^2-4x+7)/(x^2-7x+12)lt=2/3 .

Solve : 5(2x-3)-3(3x-7)=5

Solve the following equations where x in R a) (x-1)|x^(2)-4x+3|+2x^(2)+3x-5=0 b) |x^(2)+4x+3|+2x+=0 c) |x+3|(x+1)+|2x+5|=0

Multiply : 2x^(2) - 4x + 5 by x^(2) + 3x - 7

Solve: |[x^2-1, x^2+2x+1, 2x^2+3x+1], [2x^2+x-1, 2x^2+5x-3, 2x^2+4x-3], [6x^2-x-2, 6x^2-7x+2, 12x^2-5x-2]|=0.

Solve (x^2-5x+7)^2-(x-2)(x-3)=1.
