Question

What describes the number and type of the roots of the equation 4x+7=0

a. 1 imaginary root
b. 1 real root and 1 imaginary root
c. 2 real roots
d. 1 real root

Answer 1

D : One Real Root

Explanation:

Isolate "4x" by subtracting 7 from both sides.

So we get

4x = -7

Then we divide each side by 4 to get -7/4

x = -7/4 so there is only one real root.
