To simplify the expression
3p2+4q2−2p2q−q2

Answer to Problem 3MRE
3p2+4q2−2p2q−q2=p2(3−q)+3q2
Explanation of Solution
Given:
3p2+4q2−2p2q−q2
Concept Used:
- If an expression contains more than one operation between its terms and brackets, first solve the terms inside brackets and then apply division followed by multiplication, addition and subtraction.
Calculation:
To simplify the expression
3p2+4q2−2p2q−q2
First, group like terms together.
As,
3p2+4q2−2p2q−q2=3p2−2p2q+4q2−q2=3p2−2p2q+(4−1)q2=3p2−2p2q+3q2
Now, take p2 common from first two terms, as
3p2−2p2q+3q2=p2(3−q)+3q2
Now, above expression can’t be simplified further.
Thus, simplified form of given expression is
3p2+4q2−2p2q−q2=p2(3−q)+3q2

Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off?
