" 14.(i) "x^(2)-2x=0

Differentiate the following functions: 14. (i) (2x-3)^(2) (ii) (2x -3)^(100)

Solve the following equations by Sridharacharya's formula : (i) x^(2)+x+4=0 (ii) 2x^(2)-2x+3=0 (iii) sqrt(2)x^(2)+x+sqrt(2)=0 (iv) x^(2)-x+2=0 (v) 25x^(2)-30x+11=0 (vi) x^(2)+3x+5=0 (vii) x^(2)-14x+58=0 (viii) x^(2)+13ix -42=0 (ix) x^(2)-11ix-30=0

I. 15x^(2) - 2x-1=0 II. y^(2) - 9y+14 = 0

Suppose that two persons A and B solve the equation x^(2)+ax+b=0 . While solving A commits a mistake in constant term and find the roots as 6 and 3 and B commits a mistake in the coefficient of x and finds the roots as -7and-2 .Then , the equation is a) x^(2)+9x+14=0 b) x^(2)-9x+14=0 c) x^(2)+9x-14=0 d) x^(2)-9x-14=0

one root of quadratic equation 14x^(2)-x-3=0

(i) x^(2) - 5x-14 = 0 (ii) 2y^(2) +11y + 14 = 0

4 (2x-3) ^ (2) - (2x-3) -14 = 0

If X=(x:x^(2)-12x+20=0) and Y=(x:x^(2)+5x-14=0) , then X-Y=
