Question

If α and β are zeroes of X2 - 5x+ 6, then the value of (α+β) is.

Answer 1

Answer:

(α+β) = 5

Step-by-step explanation:

Equation :  $x^{2} -5x+6=0$

The roots of the equation are α & β

We know that in a quadratic equation $ax^{2} +bx=c=0$

Sum of the roots (α+β) =  $\frac{-b}{a}$

Here, a = 1 and b = -5

Therefore (α+β) = $\frac{-(-5)}{1} = 5$
