x

^{2}+ x + 3 - 4x -4x^{2}- 10"Like terms" are terms that contain the same variables raised to the same power, such as x

^{2}. Only the numerical coefficients are different (3x^{2}, -5x^{2}, etc.). The first step is to group the like terms. I've added parentheses to make it clear, but the parentheses are not required:(x

^{2}- 4x^{2}) + (x - 4x) + (3 -10)Here x

^{2}and -4x^{2}are like terms, x and -4x are like terms, and 3 and -10 are like terms. Next simplify by adding or subtracting the like terms:x

^{2}- 4x^{2}= -3x^{2}x - 4x = -3x

3 - 10 = -7

x

^{2}+ x + 3 - 4x -4x^{2}- 10 = (x^{2}- 4x^{2}) + (x - 4x) + (3 -10) =**-3x**^{2}- 3x - 7
