Answer:
-
Step-by-step explanation:
A root with square root or under root is only obtained when we take the square root of both sides. Remember that when we take a square root, there are two possible answers:
- One answer with positive square root
- One answer with negative square root
For example, for the equation:

If we take the square root of both sides, the answers will be:

Only getting one solution with square root is not possible. Solutions with square root always occur in pairs.
For given case, the roots are 6 and
. Therefore, the 3rd root of the polynomial function f(x) had to be -
It seems you made error while writing option B, it should be - square root of 5.
X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6,
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)
Answer: 42.
Step-by-step explanation:
Answer:
31 - 12=p
p= 19
Step-by-step explanation:
Hello! The answer to your question would be as followed:
Step 1:
5x - (3•5x^2)
Pull out like terms:
5x - 15x^2 = -5x • (3x - 1)
Final Result:
-5x • (3x - 1)
