+5x
Answers
Answer:
Answer:
Zeroes are 0 and \frac{-1}{5}
5
−1
Step-by-step explanation:
Given: Quadratic Polynomial , 25x² + 5x
To find: Zeroes of Polynomial and Verify the relation between zeroes and coefficient
To find zeroes we equate polynomial with 0
⇒ 25x² + 5x = 0
5x ( 5x + 1 ) = 0
5x = 0 and 5x + 1 = 0
x = 0 and x = \frac{-1}{5}

−1
Therefore, Zeroes are 0 and \frac{-1}{5}

RHS = [tex\frac{-b}{a}=\frac{-5}{25}=\frac{-1}{5}[/tex]
LHS = RHS
Hence Verified
Second Relation is Product of zeroes/roots = \frac{constant\:term}{coefficient\:of\:x^2}

LHS = αβ = 0\times]frac{-1}{5}=00×]frac−15=0
RHS = [tex\frac{c}{a}=\frac{0}{25}=0[/tex]
LHS = RHS
Hence Verified
