" 57"x^(2)-2x+(7)/(16)

Solve : (i) 2x^(2)-7x=39 (ii) x^(2)=5x (iii) x^(2)=16

Evaluate lim_(x to 4) (x^(2) - 7x + 12)/(x^(2) - 16)

Evaluate lim_(x to 4) (x^(2) - 7x + 12)/(x^(2) - 16)

Find the square root of: 49x^(4) -(7x^(2))/2 + (673 x^(2))/16 - (3x)/2 + 9

x^(7)+x^(4)-16x^(3)-16

If x is rational and 4(x^(2)+(1)/(x^(2)))+16(x+(1)/(x))-57=0 , then the product of all possible values of x is

If x is rational and 4(x^(2)+(1)/(x^(2)))+16(x+(1)/(x))-57=0 , then the product of all possible values of x is

(3.5)/(1!)x+(4.6)/(2!)x^(2)+(5.7)/(3!)x^(3)+....=

If x=(3)/(16)(3)+(3.7)/(16.32)(3)^(2)+(3.7.11)/(16.32.48)(3)^(3) +… then show that x^(2)+2x=7
