" 6."(x+2)^(3)=2x(x^(2)-1)

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)

If x^(4) - 3x^(2) - 1 = 0 , then the value of (x^(6)-3x^(2)+(3)/(x^(2))-(1)/(x^(6))+1) is :

Simplify (x+2)(x^(2)-6x+8)-(2x-3)(2x^(2)-x-1)

Observe the following pattern (1x2)+(2x3)=(2x3x4)/(3)(1x2)+(2x3)+(3x4)=(3x4x5)/(3)(1x2)+(2x3)+(3x4)+(4x5)=(4x5x6)/(3) and find the of (1x2)+(2x3)+(3x4)+(4x5)+(5x6)

lim_(xrarr0) (6^(x)-3x^(2)-2^(x)+1)/(x^(2))=?

If (x^(2)-2x-9)/((x^(2)+x+6)(x+1))=(2x-3)/(x^(2)+x+6)+(A)/(x+1) , then A is ___________.

If x-=2+2^(2//3)+2^(1//3)" then the value "(x^(3)-6x^(2)+6x) is

If x-=2+2^(2//3)+2^(1//3)" then the value "(x^(3)-6x^(2)+6x) is
