Answer 2

Answer:

Roots are not real.

PLEASE MARK MY ANSWER AS BRAINLIEST.

Step-by-step explanation:

${x}^{2} - 3x + 60 = 0$

we know that

$x = \frac{ - b + \sqrt{{b}^{2} - 4.a.c } }{2.a}$

and

$x = \frac{ - b - \sqrt{{b}^{2} - 4.a.c } }{2.a}$

$x = \frac{ - ( - 3) + \sqrt{{( - 3)}^{2} - 4.1.60 } }{2.1}$

and

$x = \frac{ - ( - 3) - \sqrt{{( - 3)}^{2} - 4.1.60 } }{2.1}$

we know that dicriminant is " D "

D =

$\sqrt{ {b}^{2} - 4.a. c}$

So, D =

${ - 3}^{2} - 4.1.60$

.: D = negative

Hence, roots are not real.
