Question

Select the correct answer. Simplify the following expression. (6x2 - 9x - 4) - (2x2 - 3x - 9)

Answer 1

4×2-6x+5

Explanation:

(6x2 - 9x - 4) - (2x2 - 3x - 9)

We can deduct (2×2) from (6×2) first: (4×2)

Then we deduct (-3x) from (-9x): (-6x)

Then we deduct (-9) from (-4): 5

Then we add everything together: (4×2-6x+5)
