Answer:
(4x -3)(√3x -1)(√3x +1)
Step-by-step explanation:
Your factoring is correct for integers. However the quadratic term can be factored further using irrational coefficients. It is the difference of the squares of (√3)x and 1, so can be factored as such.
12x³ -9x² -4x +3 = 3x²(4x -3) -(4x -3) = (3x² -1)(4x -3)
= ((√3)x -1)((√3)x +1)(4x -3) . . . . . . further factoring the difference of squares
Answer:
30:15 (simplified is 2:1)
Step-by-step explanation:
Out of the 45 times Eric flipped a coin, 30 of them landed on heads. Tails is the the only other probable occurance, so since we know that there are 15 trials left, this means that the coin landed on tails 15 times. This would give a heads to tails ratio of 30:15, but the simplified ratio would be 2:1, because that's the smallest it can be divided evenly.
45-30=15
30:15=2:1
