Answer:
Explanation:
is the equation that you've given us.
Now if we plot these two equations on the graph we notice there's an intersection at (1,-2). Therefore meaning that
.
We can prove that by doing the following calculations to prove that both sides are equal to each other.
The left side of the equal sign:
Step 1: Write the equation down:
Step 2: Substitute x for the numerical value we found.
Step 3: Find the square of
, which is itself, 2.
Step 4: Subtract 2 from 4. Which is a negative number, thus being -2.
The right side of the equal sign:
Step 1: Write the equation down:
Step 2: Substitute x for the numerical value we found.
Step 3: Find the square of
, which is itself, 4.
Step 4: Subtract 4 from 6. Which is a negative number, thus being -2.
We know that
because when substituting x with 1, we get -2 on both sides. Therefore making this statement true and valid.
