Answer: Last option.
Step-by-step explanation:
For this exercise you need to find the Discriminant.
The formula used to find the Discriminant, is the following:

In this case, given the Quadratic equation:

You can identify that:

Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.
You get that this is:

By definition, if:
Then the Quadraitc equation has 2 nonreal solutions.
Answer:
You have a picture of the problem?
try c im sorry if im wrong i tried
Let the number<span> be H T O. Ones digit = O Given that. O =10−5 ⇒ O =5. Also is given that tens digit T is 2 </span>more than<span> ones digit O ⇒ tens digit T = O +2=5+2=7. ∴ The </span>number<span> is. H 75. Given also is that "</span>number<span> is </span>less<span> than </span>200<span> and </span>greater than 100<span> " ⇒ H can take value only =1. We get our </span>number<span>as 175.</span>
Answer:
120
Step-by-step explanation:
66 + (2* 10*5)- 46
66+20×5−46
66+100−46
166−46
= 120
