If f(x) = x4 − x3 + x2 and g(x) = −x2, where x ≠ 0, what is (f ⁄g)(x)?
DerKrebs [107]
<span>The value of (f/g)(x) is determined by dividing the polynomial f(x) by the polynomial g(x) which is only equal to -x2. If we divide the first term of f(x), x4, with -x2, we arrived with an answer of -x2. For the second term, we arrive with the answer x. Similarly for the third term, we derive with an answer that is -1. Combining all the answers, we have -x2 + x - 1.</span>

-1+(-3) is blank units from -1 in the blank direction
Thepotemich [5.8K]

-1+(-3) is  3 units from -1 in the left direction

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction

because we know that

in the real line if we go 3 units in left from -1 we get -4

since in the real number line

the pattern is ................ - 5, -4, -3, -2, -1 ,0,1,2,3,4,5,............

thus we get  

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction
