Answer:
P(x) = 15x^2 + 2x + 4
Step-by-step explanation:
To simplify:
combine like terms
8x^2 + 7x^2 = 15x^2
There are no other like terms.
This equation cannot be simplified any further with the given information.
P(x) = 15x^2 + 2x + 4
Answer:
(f + g)(x) = x² - 3x + 5
Step-by-step explanation:
Here we find the sum of two functions. Combine like terms in f and g, as follows:
(f + g)(x) = x² – 4x – 2 + x + 7, or
(f + g)(x) = x² - 3x + 5
Answer:
99 m
Step-by-step explanation:
The 10 covers required ...
(10 covers) × (3 m/cover) = 30 m
So the amount remaining is ...
150 m - 30 m - 21 m = 99 m
Lee has 99 m of the fabric left.
Let's factor the following polynomial to find the roots:
x2-13x + q = 0
Factoring we have:
(x-12.5) * (x + a)
Where,
-12.5 + a = -13
a = -13 + 12.5
a = -0.5
We now look for the coefficient q:
q = -12.5 * a
q = -12.5 * (- 0.5)
q = 6.25
The polynomial will then be:
x2-13x + 6.25 = 0
Its roots are:
x1 = 12.5
x2 = 0.5
Answer:
The other root and the value of the coefficient are:
0.5 and 6.25 (Respectively)
29,060,000
When writing this out, it is important to make sure you include the commas and the exact amount of zero's by the way.
