Using (x+a)(x+b)= x2+ (a+b)x+ab
(X+4)(x+10)=(4)2+(4+10)10+4*10
= 16+140+40
=196
(X+4)(x+10)=(4)2+(4+10)10+4*10
= 16+140+40
=196
harshita072003p8v5wh:
how's x2 = 4x
how's x2 = (4)2
HEYA IT IS WRONG..
X WILL NOT BE ANY NUMBER IT IS VARIABLE
yup
it is given that value of x is 4
sorryy value is 2
square of 2 is 4
it is square

HEYA....
HERE IS YOUR ANSWER...
IDENTITY IS - [x+a] [x+b] = x^2 + [a+b]x + ab
here a = 4
b = 10
therefore - ans is--- x^2 + [10+4]x + 10*4
= x^2 + 40x + 40
hope helped...
