Question

NEED TO PASS HELP WILL GIVE BRAINLY!!!

Answer 1

Answer:

$\bigodot$ None of the other answers are correct.

Step-by-step explanation:

• $2b^2-3b+85=-5$ (Given)

• $\implies 2b^2-3b+85+5=0$

• $\implies 2b^2-3b+90=0$

• Comparing it with the general form of quadratic equation $ax^2+bx+c=0,$ we find:

• a = 2, b = -3, c = 90

• Next, we find the value of the discriminant $b^2-4ac$

• $b^2-4ac= (-3)^2-4(2)(90)=9-720=-711$

• $\because b^2-4ac$, which means the roots of the given quadratic equation are non-real or imaginary.

• Thus, last option is the correct answer.
