Answer:
the line pls?
Step-by-step explanation:
Answer:
It is a factor
Step-by-step explanation:
[x³ -7x² + 8x + 16] ÷ (x + 1)
[x³ + x² - 8x² - 8x + 16x + 16] ÷ (x + 1)
[x²(x + 1) - 8x(x + 1) + 16(x + 1)] ÷ (x + 1)
x² - 8x + 16 and tye remainder is 0.
So, yes (x + 1) is a factor
Answer:
Step-by-step explanation:
1. A square has four sides and all the sides have equal length.
2. Keeping this on mind, you must multply the lenght given in the problem by 4, as you can see below:

3. Therefore, the polynomial expresion that represents the perimeter of the square is
.
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
