Answer» Answer: 4x²-2y²+4x+2 Step-by-step EXPLANATION: Here, 1st expression= 4x + y² - 3 2ND expression = 5y² + 2x² + 5 and, 3rd expression = 2x² - 8y² Now, adding these expressions 1st expression + 2nd expression + 3rd expression = 4x + y² - 3 + 5y² +2x² +5 +2x² - 8y² = 4x² - 2y² + 4x + 2

Answer»

Answer:

4x²-2y²+4x+2

Step-by-step EXPLANATION:

Here,

1st expression= 4x + y² - 3

2ND expression = 5y² + 2x² + 5

and, 3rd expression = 2x² - 8y²

Now, adding these expressions

1st expression + 2nd expression + 3rd expression

= 4x + y² - 3 + 5y² +2x² +5 +2x² - 8y²

= 4x² - 2y² + 4x + 2
