Hint:
The expansions of certain identities are:
We are asked to simplify the given expression
The correct answer is: the simplified expression is (x2 -x3 +4x +11)/(x+2)
Step 1 of 2:
Fins the LCM of the expression 
,
Thus, the expression becomes 
,
Step 2 of 2:
Now, find the product of 
For that, simplify and cancel out the common factors
Hence, the simplified expression is 
;
LCM of two numbers or values are the least common multiples of both of them.

Write the equation in slope-intercept form of the line that passes through the points (5, 4) and (-1, 6).
The slope intercept form is y = mx + b, where m represents the slope and b represents the y-intercept. We can draw the graph of a linear equation on the x-y coordinate plane using this form of a linear equation.
Steps for determining a line's equation from two points:
Step 1: The slope formula used to calculate the slope.
Step 2: To determine the y-intercept, use the slope and one of the points (b).
Step 3: Once you know the values for m and b, we can plug them into the slope-intercept form of a line, i.e., (y = mx + b), to obtain the line's equation.
