If Fiona is to divide the first expression by the second one, clearly only the first term of the first expression is divisible. The remaining terms of the fist expression will remain as the remainder. The remainder from the division done by Fiona should be 5x - 3.
Zeroes:
We must solve

To do so, we define the auxiliary variable
. The equation becomes

The quadratic formula yields the solutions

Substituting back
gives

So, the zeroes are -6, -3, 3, 6.
Turning points:
Turning points are points where a function stops being increasing to become decreasing, or vice versa. Since functions are increasing when their first derivative is positive and decreasing when it's negative, turning points are points where the first derivative is zero.
We have

If we set the derivative to be zero, we have

So, the derivative is zero if x=0 or

Answer:
No, these triangles cannot lie on the same line.
Step-by-step explanation:
Step-by-step explanation: For two triangles to lie on the same line they must have the same slope. slopes are negative because the triangles are leaning to the left.
Answer:
4x-8
Step-by-step explanation:
y=-x2+6x-8
y=4x-8
