Question

Find the sum and product of the zeroes of the quadratic polynomial 2x²-5x-6

Answer 1

Step-by-step explanation:

$2 {x}^{2} - 5x - 6$

$a = 2 \\ b = - 5 \\ c = - 6$

$\alpha + \beta = \frac{ - b}{a}$

$\alpha \times \beta = \frac{c}{a}$

$\alpha + \beta = \frac{5}{2 }$

$\alpha \times \beta = \frac{6}{5}$

sum of zero=5/2

product of zero =6/5
