If `(7/4x-2/3)/(4/3x+2)=1/2` then `x=`

If (x^(4))/((x-1)(x-2))=x^(2)+3x+7+(A)/(x-2)+(B)/(x-1) then A=

If (x^(4))/((x-1)(x-2))=x^(2)+3x+7+(A)/(x-2)+(B)/(x-1) then A=

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

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

Evaluate int ((8x+13)/sqrt(4x+7)) dx (A) 1/3 (4x+7)^(3/2) - 1/2 (4x+7)^(1/2) + c (B) 1/6 (4x+7)^(5/2) - 2/3 (4x+7)^(3/2) + c (C) 1/3 (4x+7)^(5/2) - 1/2 (4x+7)^(3/2) + c (D) (4x+7)^(3/2) - 1/2 (4x+7)^(1/2) + c

Evaluate int ((8x+13)/sqrt(4x+7)) dx (A) 1/3 (4x+7)^(3/2) - 1/2 (4x+7)^(1/2) + c (B) 1/6 (4x+7)^(5/2) - 2/3 (4x+7)^(3/2) + c (C) 1/3 (4x+7)^(5/2) - 1/2 (4x+7)^(3/2) + c (D) (4x+7)^(3/2) - 1/2 (4x+7)^(1/2) + c

Solve the equation (3x^4+x^2-2x-3)/(3x^4-x^2+2x+3)=(5x^4+2x^2-7x+3)/(5x^4-2x^2+7x-3)

Show that the expression (x^2-3x+4)/(x^2+3x+4) lies between 1/7 and 7 for real values of x.
