the difference between 2x2+4xy-3 and x2-2xy-4 is
I will be happy to critique your work on this.
To find the difference between the two expressions, we need to subtract the second expression from the first expression. Let's go step by step.
First, let's write the given expressions side by side:
Expression 1: 2x^2 + 4xy - 3
Expression 2: x^2 - 2xy - 4
Now, we can subtract term by term. Note that when subtracting, we change the signs of each term in Expression 2 and then combine like terms.
Step 1: Subtract the x^2 terms:
2x^2 - x^2 = x^2
Step 2: Subtract the xy terms:
4xy - (-2xy) = 4xy + 2xy = 6xy
Step 3: Subtract the constants:
-3 - (-4) = -3 + 4 = 1
Combining all the results above, the difference between the two given expressions is:
x^2 + 6xy + 1
