What are the roots of the polynomial equation? (picture below)
2 answers:
Answer:
-9, 0, 7
Step-by-step explanation:
Finding the roots of a polynomial equation is the same as solving the equation. So, simply figure out which values make the equation equal 0.
If multiplication is involved, then 0 is always an answer (or root). Because anything multiplied by 0 is always 0.
7 is also a root:
7 - 7 = 0
Same with -9:
-9 + 9 = 0
Answer:
x = - 9, x = 0, x = 7
Step-by-step explanation:
Given
x(x - 7)(x + 9) = 0 ← in standard form
Equate each factor to zero and solve for x
x = 0 ⇒ x = 0
x - 7 = 0 ⇒ x = 7
x + 9 = 0 ⇒ x = - 9

Answer:

Step-by-step explanation:
Just Square the numbers like a normal equation.
4² = 16
9² = 81
This gives us 
or 0.198 as a decimal (approx)
The sum is 41.22 because first you turn all of the fractions into decimals and then it’s easier to add them all together all at once.
