`x^2-15 x+56`

Calculate the value of x in the following equation :- (i) x^(2)-5x+6=0 (ii) x^(2)-9x+20=0 (iii) x^(2)-15x+56=0 (iv) x^(2)-16x+63=0

Calculate the value of x in the following equation :- (i) x^(2)-5x+6=0 (ii) x^(2)-9x+20=0 (iii) x^(2)-15x+56=0 (iv) x^(2)-16x+63=0

Factorise the following : x^2 + x - 56

x^(2)+15x+56=0

In the following questions two equation numbered I and II are given You have to solve both equations and . . . . . (i) x^(2)=15x-56=0 (ii) y^(2)-23y+132=0

In the following question two equations are given in variables x and y. you have to solve these equations and determine the relation between x and y. I. x^(2) - 15x + 56 = 0 II. y^(2) - 17y + 72 = 0

Factorise: x^(2) + x-56

Factorise: x ^(2) + 15x + 56

The term independent of x in the expansion of (1-x +2x^3)(x^2-1/x)^8 is given by - (A) -56 (B) 56 (C) 0 (D) none of these
