Answer 1

B not real is the answer hope it helps

Answer 2

✰ Question :-

• What is the nature of the roots of quadratic equation : 4m² - 8m + 9 = 0 ?

✰ Solution :-

Equation :- ➭ 4m² - 8m + 9 = 0

So, we need to check whether nature of the roots is

• real
• not real
• real and equal
• real and unequal

Now, To determine the nature of the roots of quadratic equation , we need to calculate the discriminant, that is b² - 4ac .

So,lets substitue the values and check :-

➯ b² - 4ac

➯ -8² - 4(4)(9)

➯ 64 - 144

➯ -80 ﹤ 0

∴ Quadratic equation have non - real roots.
