Same as before
total=(2w+75)(2w+35)=4w²+220w+2625
pool=75 times 35=2625
minus pool from total
4w²+220w+2625-2625=4w²+220w
Answer:
4v-6.3w+9.8
Step-by-step explanation:
If you distribute the negative sign (same as distributing -1), then you get -(-4v) + (-6.3w) - (-(9.8))
Basically it's switching the signs
Hope that helped :)

• First way to solve:
We'll manipulate the expression of the equation:

If we have y=0:

Then, the function has one real zero (x=3) and two imaginary zeros (4i and -4i).
Answer: B
• Second way to solve:
The degree of the function is 3. So, the function has 3 complex zeros.
Since the coefficients of the function are reals, the imaginary roots are in a even number (a imaginary number and its conjugated)
The function "has only one non-repeated x-intercept", then there is only one real zero.
The number of zeros is 3 and there is 1 real zero. So, there are 2 imaginary zeros.
Answer: B.
