Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
2

Step-by-step explanation:
When n is multiplied by -5/8 and the product is equal to -4, it's really saying
-5/8n = -4
To solve an equation like this we can use properties of equality
For this problem there is only one step, being dividing both sides by -5/8
-4 divided by -5/8 = 32/5
Answer: 32/5 or 6 2/5
