Answer 1

Answer:

mark me brainlist please

Answer 2

Step-by-step explanation:

10x² + 3x - 1 ( after rearranging)

10x² + 5x - 2x - 1 ( 5 - 2 = 3)

5x ( 2x + 1 ) -1 (2x + 1) ( taking common)

(5x - 1)(2x + 1)

alpha = 1/5

bita = -1/2

alpha + bita = -b/a

1/5 - 1/2 = -3/10

-3/10 = -3/10 hence, verified

alpha × bita = c/a

1/5 × -1/2 = -1/10

-1/10 = -1/10 hence, verified
