Question

solve the following quadratic equations by factorization

Answer 1

QUESTION (31) :- x^2+[a+1/a]x+=0

SOLUTION:-

=》 x^2+[1+1]x+1=0
=》 x^2+(2)x+1=0
=》 x^2+2x+1=0

TREE METHOD :-

x^2

2x

=》 x^2+1x+1x+1
lets take out common factors
=》 x(x+1)+1(x+1)
=》(x+1)(x+1)
Therefore x+1 is a factor

x+1 = 0
x=0-1
x=-1
