Note that it said find "a" formula for P(x). We can infer from this as there are multiple possibilities.
In fact, there are many possible P(x) that fits the bill.
You got the most important part correct, namely
(x+5)(x-5)^2.
In general, P(x)=A(x+5)(x-5)^2 will work, but we need to satisfy also y-intercept of P(0)=-75.
If we expand the expression, we get
P(x)=A*x^3A-5A*x^2-25A*x+125A
=>
P(0)=125A.
So setting A=-3/5 => P(0)=-75 as required.
or
P(x)=-3/5(x+5)(x-5)^2
will satisfy all requirements.
It would be nice exercise for you to confirm that it is indeed the polynomial required.
Answer:
-12c-5
Step-by-step explanation:
Step 1- Distribute into the parenthesis(Since there's nothing next to the parenthesis to multiply, there is a 1).
-9c-1(5-3c)
-9c-5(1)-3(1)c
Step 2- Multiply,
-9c-5-3c
Step 3- Add common variables.
(-9c-3c)-5
-12c-5
Minimum degree
ok, so
a first degree (y=mx+b) can cross at most 1 time
a 2nd degree (y=ax²+bx+c) can cross at most 2 times
so therfor we see that a nth degree polynomial can cross or touch at most n times
so 7 times means 7th degree
minimum degree is 7th degree
Step-by-step explanation:
<1 = 90 - 32
= 58
bd is a traversal to parallel line ab and dc
<1 = <bdc ( alternate angles) = 58
in right triangle edc
90 - 58 = <3 = 32
<2 = 58
