How can I improve translating words into math?
Ex) pg 47. #2, I got the answer A, but the correct one is C?
What am I mixing up? It happened with multiple questions
In the “Proving Grounds” Quiz 1 #5, this question is given:
p(x) = ax^2 + bx + c
q(x) = ax^2 + bx + d
The functions p(x) and q(x) are defined above, and a, b, c, and d are constants. If x – 3 is a factor of p(x) and d is 8 greater than c, what is the remainder when q(x) is divided by x – 3?
In your answer explanation, you state:
“…We know that, as a general rule, the remainder when a polynomial f(x) is divided by x – a is f(a).”
Can you explain this further?
Is there a way to solve this system of equations without using the quadratic formula (or graphing)?
f(x) = –2/3 x + 4
g(x) = 3(x + 2)^2 – 4
How many solutions does the system above have?

For the past few months I’ve been working on an online, interactive version of PWN the SAT: Math Guide, and I’m excited to announce that subscriptions are available now in the PWN store!
The country hall charges a rental fee of $1000 and at least $3000 for food. Olivia is planning a class reunion. If she had chosen a buffet that costs $38.56 per person what is the minimum possible number of people who must attend to support the expense?
