Question

(α+β) of the eqn 7x2-8x -10=0 is 

​

Answer 1

Answer:

answer is 8/7

Step-by-step explanation:

the formula is -b/a i.e, (- coefficient of x) / coefficient of x^2

Answer 2

$\huge\underline\mathtt\orange{Solution}$

7x² - 8x - 10 = 0

a = 7 , b = -8 , c = -10

$\alpha + \beta = \frac{ - b}{a} \\ \\ \alpha + \beta = \frac{ - ( - 8)}{7} \\ \\ \alpha + \beta = \frac{8}{7}$
