2* + is one factor of the polynomial 2x² - x-1, then find the
other factor.
clima which is parallel to y-axis​

Answer 1

Answer:

the line (2x+y+1)+\lambda(x-y+1)=0(2x+y+1)+λ(x−y+1)=0 is parallel to y-axisy−axis then value of \lambdaλ is ?

ANSWER

Parallel to y-axis \Rightarrow y=0⇒y=0

2x+y+1+\lambda x-\lambda y+\lambda =02x+y+1+λx−λy+λ=0

x(2+\lambda )+y(1-\lambda )+(1+\lambda )=0x(2+λ)+y(1−λ)+(1+λ)=0

coefficient of y=0y=0

1-\lambda =0\Rightarrow \lambda =11−λ=0⇒λ=1
