Question

If alpha and beta are the zeroes of 2x square + 5 (x-2) ,then find the products of alpha and beta

Answer 1

$2 {x}^{2} + 5(x - 2) \\ 2 {x}^{2} + 5x - 10 \\ \: on \: comparing \: with \: standard \: eq \\ a {x}^{2} + bx + c \\ \alpha \beta = \frac{c}{a} \\ \alpha \beta = \frac{ - 10}{2} \\ \alpha \beta = - 5$

Answer 2

Answer:

p(x)= 2x²+5(x-2)

p(x)= 2x²+5x- 10

alpha + beta = -b/a

alpha×beta = c/a
