Question

What are the zeros of the polynomial 4s2-5s+1

Answer 1

Answer:

Zeroes of the given polynomial are 1 & 1/4.

Step-by-step explanation:

Given expression = 4s2 - 5s +1

Let us assume, the expression equals to zero. Then, 4s2-5s+1 = 0

By splitting the middle the middle term, we get,

4s2-4s-1s+1=0

Next,

4s(s-1)-1(s-1)=0 (by taking common)

Now,

s-1=0 (or) 4s-1=0

s=1 (or) s=1/4

Therefore, zeroes of the given polynomial are, 1 and 1/4.
