Answer:
Step-by-step explanation:
<u>Factor x³ + 2x:</u>
1. <u>The common factor is x, then</u>:
- 2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)
2. Factor x² + 2 is not linear therefore we discard it.
-1 19/78 ...... all you have to do is go 1/6 steps up because its negative 1 1/3
You need to divide the 3 blocks of clay by the 4 friends. 3 goes in the dividend and the 4 is outside. 3 divided by 4 is equal to 0.75 or 3/4, so each friend gets 0.75 or 3/4 clay
For this fraction, we have (3x+2) in both the numerator and the denominator. So, they will be cancelled together.
Then we can notice that we can divide the coefficients in the numerator and the denominator by 9 as 36/9 = 4 and 9/9 = 1
So, the expression now becomes:
(x+7) / 4(x-5) which is the simplest form.
