`(x^2+6x-7)/(x^2+1)<=2`

lim_(x rarr oo)(9x^(2)-2x-7)/(6x^(2)+5x+1

Evaluate the following limits : underset(hrarr-(1)/(2))"lim"(6x^(2)-7x-5)/(2x^(2)-x-1)

int (6x^(3) + 5x^(2)-7)/(3x^(2)-2x-7)dx

Compute the following limits. Lt_(xtooo)(6x^(2)-x+7)/(8x^(2)-7x+3)

If x, y , in , R , then the value of the determinant A=[{:((5^x+5^(-x))^2,(5^x-5^(-x))^2,1),((6^x+6^(-x))^2,(6^x-6^(-x))^2,1),((7^x+7^(-x))^2,(7^x-7^(-x))^2,1):}] is

((6x^(4)+8x^(3)+27x^(2)+7)/(3x^(2)+4x+1))

int(5x^(8)+7x^(6))/(x^(2)+1+2x^(7))dx is equal to (a) (x)/(x^(2)+1+2x^(7))+C( b) (x^(7))/(x^(2)+1+2x^(7))+C (c) (x^(6))/(x^(2)+1+2x^(7))+C(d)x^(2)+1+2x^(7)+C

int (5x^(8)+7x^(6))/((x^(2)+1+2x^(7))^(2))dx=

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.
