(m+2)⁴ = ((m+2)²)²
= (m² + 4+ 2m)²
= m⁴ + 8 + 4m² + 8m² + 16m + 4m³ .........( (a+b+c)² = a²+b²+c²+2ab+2bc+2ac)
= m⁴ + 8 + 12m² + 16m + 4m³
Answer:

Step-by-step explanation:
Based on the information given we can say the two points are (-5, 4) and (-10, 0). An x-intercept is where the line crosses the x-axis giving us a y value of 0.
So, we will use the following formula, where m is equal to the slope.

Now we will plug in the x and y values given above, (-5, 4) and (-10, 0).

Note: In the denominator of the first line, the -5 was changed to a 5 because in the original equation, we are told to subtract. When you have two negatives they cancel each other out.
