5x to the second power+4+6y-1+3y-4x to the second power-5
Combine like terms
The like terms in the expression are 5x^2 and -4x^2.
Combining these terms, we get 5x^2 - 4x^2 = x^2.
The like terms in the expression are 6y and 3y.
Combining these terms, we get 6y + 3y = 9y.
The simplified expression is x^2 + 9y - 2.
To combine like terms, let's group them together:
5x^2 - 4x^2 + 4 + (-1) - 5 + 6y + 3y
Combining the x^2 terms:
(5x^2 - 4x^2) + 4 + (-1) - 5 + 6y + 3y
Simplifying:
x^2 + 4 + (-1) - 5 + 6y + 3y
Combining the constant terms:
(x^2) + (4 - 1 - 5) + (6y + 3y)
Simplifying:
x^2 + (-2) + (9y)
The final expression after combining like terms is:
x^2 - 2 + 9y
