Question

If'a' and 'b' are zeros of x² + 5x + 8 then the value of (a +B) is – (i) 5 (ii)-5 (iii) 8​

Answer 1

Answer:

The value of α+β is -5.

Step-by-step explanation:

Since we have given that

$x {}^{2} + 5x + 8$

Let α and β are the zeroes of the above quadratic equation.

As we know the relation between zeroes and the coefficients of quadratic equation in the form of ax²+bx+c=0.

$\alpha + \beta = - b \div a = - 5 \div 1 = -5$

Hence, the value of α+β is -5.
