Remainder Theorem to Evaluate

When p(x) = 9x⁴- 45x³ + 37x² + x +2 is divided by x - 2, a student can determine the remainder by evaluating p(2). What is the value of p(2)?

• p(2) = 656

• p(2) = 652

• p(2) = -64

• p(2) = -368

Find the remainder when 8x² - 5x + 1 is divided by x - 2

• -1

• 0

• 21

• 23

Answer explanation

Let p(x)= 8x² - 5x + 1 the zero of the polynomial x - 2 is 2 Evaluate p(2) p(2) = 8(2)² -5(2) + 1 = 32 - 10 + 1 = 23 So, by the Remainder Theorem, 23 is the remainder when 8x² - 5x + 1 is divided by x - 2 Alternatively, we can do the long division. When we divide 8x² - 5x + 1 by x - 2, we get 23 as the remainder Hence, option 4 is the correct answer.
