(a) x² - x - 12 (b) x² + x - 12 (c)- 12x (d) x 12x - I.
2​

Answer 1

Answer:

it's correct option is b) x^2+x-12

Answer 2

Answer:

sum of roots = $\alpha +\beta$ = -b/a = 1/1

product of roots = $\alpha \beta$ = c/a = -12/1

Step-by-step explanation:

so, from the above data we get to know that a = 1

now b = -1     (as in above equation -b = 1  .... so b = -1)

c=-12

lets substitute the vales in the general quadratic equation form which is,

$ax^{2} + bx + c = 0$

which is,

$x^{2} - x - 12$     (option a)

thus this is the required quadratic equation,
