yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy
-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)
9x³ - 19x² - 17 = (x - a)(x - b - ic)(x - b + ic)
Answer:
C
Step-by-step explanation:
Note that the measurements of the side of the squares are the same.
Area = base x height
Area = length x width
The area given is 400
Root 400 to get the length of the sides
√400 = 20
20 in. is your side measurement
