X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)
Answer:
a=3
b=-5
c=2
Step-by-step explanation:
Because first arrange them in decreasing order by their variables powers like this 3x²-5x+2 after that take the the coefficients
Ok so you have 4, x^6 / 2, x^4. Now divide the coefficient so 4/2=2. So 2 x^6/x^4, now subtract the numerator by the denominator so x^6-x^4=x^2 so now you have 2x^2
Answer: 2x^2
ax+r=7
Move ax to the other side. +positive ax changes to -negative ax
ax-ax+r=7-ax
r=7-ax
Answer: r=7-ax or r=-ax+7 ( same thing) but rearranged
