1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18
Answer:
5 + 2(3 + 2x) = x + 3(x + 1) (2nd one)
Step-by-step explanation:
The top and bottom question's are all real numbers and the third one is 0
Answer:
1.375
Step-by-step explanation:
Answer:
36-72
Step-by-step explanation:
all you do is multiply the -9 by the numbers in the parenthesis. If you are multiplying two negatives or two positives then the outcome if positive. If you multiply a positive and a negative the outcome is negative.
2.4 becase if you add a zero it would still be the same number but it would be 2.40. This is less than 2.42 and more than 2.0
