The value of λ is - 2 and other zero is also - 2.
<h3>Justification:</h3>
Let <u>p(x) = 2x² + 3x + λ</u>
<u>Its one zero is 1/2</u>, so p(1/2) = 0
p(1/2) = 2 × (1/2)² + 3 × 1/2 × λ
⇒ 1/2 + 3/2 + λ = 0 ⇒ 4/2 + λ = 0
⇒ 2 + λ = 0 ⇒ λ = - 2
<u>Let the other zero be α</u>,
Then α + 1/2 = - 3/2 ⇒α = - 3/2 - 1/2 = - 2
Bran has to make in all to walk a total of 28 kilometers : 4 x 2 = 8 ( trips )
ok done. thank to me :>
It’s A . Not d so
-3 < y < infinity
