Question

If the path traced by the car has zeroes at-1 and 2, then it is given by (a) x2 +x+2 (b) x2-x+2 (c) x2-x-2 (d) x +X-2​

Answer 1

Answer:

c

Step-by-step explanation:

c is the correct option

alfa × beta =c/a

= -1×2 = -2

= alfa+beta = -b/a

= -1+2 = 1

= x²- (alfa+beta)x +alfa×beta

= x²- 1x - 2

= x² - x - 2
