" 2."5(x-5)(x+5)=55

Factorize the following polynmials: (1) x^(2)-4x-5 =x^(2)-5x+x-5 =x(x-5)+1(x-5) =(x-5)(x+1)

The coordinates of the point on the curve y=6x-x^(2) the tangent at which is parallel to the line y=-4x are (a) (5,5) (b) (5,-5) (c) (-5,5) (d) (-5,-5)

The co-ordinate of the point on the curve y = 6x - x^2 , the tangent at which, is parallel to the line y =-4x are ....... A) (5,5) B) (5,-5) C) (-5,5) D) (-5,-5)

Simplify: (155x155x155-55x55x55)/(155x155+155x55+55x5)

B-2. B-2. The value of 5 5 The value of f55°. 55", 5x dx is equal to 5 5xX 5 (B) 555% (en 5)" + C 6 D) (in5+ C (Ay (C) -c 3 (en 5)

The factors of x^4-x^2-10x-25 are (a) (x^2+3x+5)(x^2-3x+5) (b) (x^2+3x+5)(x^2+3x-5) (c) (x^2+x+5)(x^2-x+5) (d) none of these

Solve: (x+5)/(2-x)+2((2-x)/(x+5))=3[x!=2,-5]

Solve: 8x - 5 = 3x + 55

Assertion (A) : (1)/(5)+(1)/(3.5^(3))+(1)/(5.5^(5))+(1)/(7.5^(7))+…(1)/(2)log((3)/(2)) Reason (R ) : If |x| lt 1 then log_(e )((1+x)/(1-x))=2(x+(x^(3))/(3)+(x^(5))/(5)+…)
