Compare given polynomial with quadratic polynomial
, we get:
a=25, b=15, c=-4
Step1: find product of a and c which is 25*-4= -100
Step2: find two numbers whose product is ac and sum is b that is product is -100 and sum is 15
We see that 20 and -5 satisfy condition of step2.
Step3: Break middle term of into two parts -100x and +15x then proceed factor by grouping.
Hence final answer is .
Answer:
coordinate of the other endpoint is (-9,-2)
Step-by-step explanation:
Given that a segment has endpoints at (1, -2). The midpoint is at (-4, -2).
Now we need to find about what are the coordinates of the other endpoint.
let the coordinates of other end points are (x,y)
Then mid point of (1,-2) and (x,y) is given by mid point formula:
hence coordinate of the other endpoint is (-9,-2)
