Simplifying 4y2+5y+2+8y2+4y+54y^2 + 5y + 2 + 8y^2 + 4y + 5

To simplify the expression 4y2+5y+2+8y2+4y+54y^2 + 5y + 2 + 8y^2 + 4y + 5, apply the method of combining like terms. Locate the terms sharing the exact same variables and exponents: the y2y^2-terms are 4y24y^2 and 8y28y^2, the yy-terms are 5y5y and 4y4y, and the standalone constants are 22 and 55. Add the numerical coefficients for each of these identical groups. The y2y^2-terms sum to 12y212y^2, the yy-terms sum to 9y9y, and the constants combine to 77. The fully simplified expression is 12y2+9y+712y^2 + 9y + 7.
