5. Solving Exercise 7.40 Page 45 Mathematics Textbook Grade 7
Problem Statement: In a math club game, the host writes down the expression on the board:
The rule is that after the host reads a certain number a, the teams must calculate the value of P(x) at x = a. The team that calculates correctly and fastest wins.
When the host announced a = 5, Square immediately calculated P(a) = 15 and won the game. Do you know how Square did it?
Solution Guide:
Simplify polynomial P(x) and then substitute a = 5 into the simplified polynomial.
Answer:
Therefore, when the host announced a = 5, Square only needed to substitute a = 5 into the expression P(x) = 3x to easily calculate: P(3) = 3.5 = 15.
