Solve sqrt(5x^(2)-6x+8)-sqrt(5x^(2)-6x-7)=1

Find the integral of 1/(sqrt(x^(2)-a^(2))) with respect to x and evaluate int1/(sqrt(x^(2)+6x-7))

Solve sqrt(5x^2-6x+8)-sqrt(5x^2-6x-7)=1.

Solve sqrt(5x^2-6x+8)-sqrt(5x^2-6x-7)=1.

Solve sqrt(5x^2-6x+8)-sqrt(5x^2-6x-7)=1.

Solve sqrt(7+ 6x - x^(2)) = x+1

lim_(x->0)[((sqrt(x)-sqrt(7))(sqrt(x)+sqrt(7)))/(x-7)]

Find the integral of (1)/(sqrt(x^(2)-a^(2))) with respect to x and hence evaluate int(dx)/(sqrt(x^(2)+6x-7)) .
