int sqrt(x^(2)+8x-6)dx

Choose the correct answer int sqrt(x^(2)-8x+7)dx(A)(1)/(2)(x-4)sqrt(x^(2)-8x+7)+9log|x-4+sqrt(x^(2)-8x+7)|+C(1)/(2)(x+4)sqrt(x^(2)-8x+7)+9log|x+4+sqrt(x^(2)-8x+7)|+C(C)(1)/(2)(x-4)sqrt(x^(2)-8x+7)-3sqrt(2)log|x-4+sqrt(x^(2)-8x+7)|+(1)/(2)(x-4)sqrt(x^(2)-8x+7)-((9)/(2))log|x-4+sqrt(x^(2)-8x+7)|

int sqrt(8+2x-x^(2))dx

int sqrt((4+8x-5x^(2)))dx

int(1)/(sqrt(x^(2)+7))dx

Choose the correct answer: int sqrt(x^2-8x+7) dx is equal to:
