Answer:
there are no real roots of this equation... middle term is not possible.
Step-by-step explanation:
you can say this by applying b² - 4ac if you've studied it .. here
b is coefficient of x
a is coefficient of x²
a is coefficient of x² and
a is coefficient of x² and c is constant
if b² - 4ac < 0 i.e if it comes out to be a negative value than it has no real roots .
in this one
b² - 4ac = (-288)² - 4(7)(10058)
= 82944 - 281624
= -198680
this value is less than zero (it is negative)
therefore this equation has no real roots
