Question

2. Simplify. 10(x + 2)(x – 3) 5(x - 3)(x + 6)

Answer 1

Answer:

$10(x + 2)(x - 3) \\ 10x + 20 \times x - 3 \\ 10 {x}^{2} + 17$

$5(x - 3)( x + 6) \\ 5x - 15 \times x + 6 \\ 5 {x}^{2} - 9$

Answer 2

Answer:

If it's all one multiplication problem:

50x^4  +  100x^3  −  1350x^2  +  5400

Just 50x to the 4th power

plus 100x to the 3rd power

plus 1350x to the 2nd power

plus 5400

If it's two separate problems:

10x^2  -  10x  -  60

5x^2  +  15x  -  90
