Answer:
Step-by-step explanation:
Let's examine the following general product of two binomials with variables x and y in different terms:
so we want the following to happen:
Notice as well that means that those two products must differ in just one unit so, one of them has to be negative, or three of them negative. Given that the product
, then we can consider the case in which one of this (b or d) is the negative factor. So let's then assume that
are positive.
We can then try combinations for such as:
Just by selecting the first one
we get that
and since
This quadratic equation give as one of its solutions the integer: d = -2, and consequently,
Now we have a good combination of parameters to render the factoring form of the original trinomial:
which makes our factorization:
Answer:
It travel at the rate of <u>500 miles per hour</u>.
Step-by-step explanation:
Given:
Ewans flight is scheduled to travel 1,750 miles in 3.5 hours.
Now, to find the rate it travel per hour.
Distance = 1,750 miles.
Time = 3.5 hours.
So, to get the rate we put formula:
Therefore, it travel at the rate of 500 miles per hour.
Slope intercept form is 
, where 'm' is the slope and 'b' is the y-intercept.
Subtract 6x to both sides:
Divide 5 to both sides:
Subtract 6x to both sides:
Divide 5 to both sides:
