Question

Can someone help me with this please

Answer 1

Answer:

1. x² – 11x + 24

2. a² + 5a + 6

Step-by-step explanation:

1. (x – 3)(x – 8) =?

Use the entities in the first bracket to multiply the second bracket. This is illustrated below:

(x – 3)(x – 8)

x (x – 8) – 3(x – 8)

x² – 8x – 3x + 24

x² – 11x + 24

Thus, the product of (x – 3)(x – 8) is

x² – 11x + 24

2. (a + 3)(a + 2) =?

Use the entities in the first bracket to multiply the second bracket. This is illustrated below:

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

a² + 2a + 3a + 6

a² + 5a + 6

Thus, the product of (a + 3)(a + 2) is:

a² + 5a + 6
