Find the sum and product of the zeroes of the polynomial x² - 6x + 5...

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

\longmapsto\tt\bold{{x}^{2}-6x+5}

By Splitting Middle Term : -

\longmapsto\tt{{x}^{2}-(5x+1)+5=0}

\longmapsto\tt{{x}^{2}-5x-1x+5=0}

\longmapsto\tt{x(x-5)-1(x-5)}

\longmapsto\tt{(x-1)(x-5)}

  • x = 1
  • x = 5

So , 1 and 5 are the zeroes of polynomial x²-6x+5....

_______________________

Here : -

  • a = 1
  • b = -6
  • c = 5

Sum of Zeroes : -

\longmapsto\tt{\alpha+\beta=\dfrac{-b}{a}}

\longmapsto\tt{5+1=\dfrac{-(-6)}{1}}

\longmapsto\tt\bold{6=6}

Product of Zeroes : -

\longmapsto\tt{\alpha+\beta=\dfrac{c}{a}}

\longmapsto\tt{5\times{1}=\dfrac{5}{1}}

\longmapsto\tt\bold{5=5}
