Question

WHat is the product of (a + 3)(a - 2)
What is the product of (x^2 + 4)(x^2 - 4)

What is the product of (x2 + 3x + 1)(x2 + x + 2) for this one write your answer in the descending power of x

Answer 1

(a + 3)(a - 2)

a(a) - a(2) + 3(a) +3(-2)

a² - 2a + 3a - 6

a² + a - 6

The product of (a + 3)(a - 2) : a² + a - 6.

Answer 2

(x² + 4)(x² - 4)

x²(x²) - 4x² + 4x² - 16

Apply the power rule

x⁴ - 16

The product of (x² + 4)(x² - 4) : x⁴ - 16.

Answer 3

(x² + 3x + 1)(x² + x + 2)

x²(x²) + x²(x) + 2(x²) + 3x(x²) + 3x(x) + 3x(2) + x² + x + 2

x⁴ + x³ + 2x² + 3x³ + 3x² + 6x + x² + x + 2

x⁴ + 4x³ + 6x² + 7x + 2.
