Answer:
.......................
Step-by-step explanation:
Since, the coordinates of the midpoint of line GH are M.
The coordinates of endpoint G are (-4,1)
We have to determine the coordinates of endpoint H.
The midpoint of the line segment joining the points and is given by the formula .
Here, The endpoint G is (-4,1) So,
Let the endpoint H be
The midpoint coordinate M is .
So,
Now,
So, the other endpoint H is (-9,-13).
The expression is simplified to 10x² + 48x + 3 =0
<h3>How to determine the value</h3>
Given the expression as;
We take the numerators have the same base, then we have;
(4x+1)(x+2) + 4(x(x+ 15) = -2x² + 21x - 1
expand the bracket
4x² + 8x + x + 2 + 4(x² + 15x) = -2x² + 21x - 1
4x² + 8x + x + 2 + 4x² + 60x = -2x² + 21x - 1
collect like terms
4x² + 4x² + 2x² + 8x + x + 60x - 21x = - 1 - 2
Add or subtract like terms
10x² + 48x = -3
Make into a quadratic equation
10x² + 48x + 3 =0
Thus, the expression is simplified to 10x² + 48x + 3 =0
