4^(x)-3^(x-(1)/(2))=3^(x+(1)/(2))-2^(2x-1)+7x=?

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=

Add: (3x^(2) - (1)/(5)x + (7)/(3)) + ((-1)/(4)x^(2) + (1)/(3)x - (1)/(6)) + (-2x^(2) - (1)/(2)x + 5)

(x+1)(x+2)(x+6)=x^(3)+9x^(2)+4(7x-1)

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

" If (3x^(3)-8x^(2)+10)/((x-1)^(4))=(3)/(x-1)+(1)/((x-1)^(2))-(7)/((x-1)^(3))+(k)/((x-1)^(2)) then "k=

If x^(2)+3x+1=0 then find x^(3)+(1)/(x^(3)),x^(4)+(1)/(x^(4)),x^(2)-(1)/(x^(2)),x^(2)+(1)/(x^(2))

(7x^(3)+3x^(2)-x+1)/(x+1)=(ax^(2)+bx+c)-(2)/(x+1)

Let the root of equation (3x^(3)-x^(2)+x-1)/(3x^(3)-x^(2)-x+1)=(4x^(3)+7x^(2)+x+1)/(4x^(3)+7x^(2)-x-1) be x_(1),x_(2),x_(3) then the value of x_(1)+x_(2)+x_(3) is

Check whether the following are quadratic equations : (1) (x-1)^(2)=2(x-3) (2) x^(2)-2x=(-2)(3-x) (3) (x-2)(x+1)=(x-1)(x+3) (4) (x-3)(2x+1)=x(x+5) (5) (2x-1)(x-3)=(x+5)(x-1) (6) x^(2)+3x+1=(x-2)^(2) (7) (x+2)^(3)=2x(x^(2)-1) (8) x^(3)-4x^(2)-x+1=(x-2)^(3)
