f(x) = x³ + 2x² + x
f(x) = x.(x² + 2x + 1)
f(x) = x.(x + 1)²
So, f(x) = 0 when x = 0 or when x = -1
But
f(x) = x.(x + 1)² = x.(x + 1).(x + 1)
So we have three roots, x = 0, x = -1 and x = -1, although two of them are equal.
So we have a multiple zero x = -1 with a multiplicity 2.

<u>task №6 only!</u>
Given: 6x+2y=12.
a) 2x+2y=12; (to use different slop);
b) 6x+2y=14; (to use different number on the right part of the given equation);
c) 3x+y=6; (to mulptiply or divide the both parts of the given equation by the same number).
Note, all the given solutions are not the only.
Answer:
4 blocks of cream cheese
Step-by-step explanation:
there are 16 Ounces in a pound.
You have 4 ounces of cream cheese. 4 is 25% of 16 so we subtract .25 from the required amount which is 2.25.
NOW we need 2 pounds. well, each block is 8 ounces, and we need in total 32 ounces. 32/8=4 blocks
