Simplify by combining like terms.
the number x and the square root of 18, subtract 3 and the square root of 8x^2.
Is this what you meant?
x%2Asqrt%2818%29-3%2Bsqrt%288x%5E2%29
x%2Asqrt%289%29%2Asqrt%282%29-3%2Bsqrt%284x%5E2%29%2Asqrt%282%29
x%2A3%2Asqrt%282%29-3%2B2x%2Asqrt%282%29
3x%2Asqrt%282%29-3%2B2x%2Asqrt%282%29
%283x%2B2x%29%2Asqrt%282%29-3
highlight%285x%2Asqrt%282%29-3%29
This can also be written 5%2Asqrt%282%29x-3
or is this what you meant:
x%2Bsqrt%2818%29-3%2Bsqrt%288x%5E2%29
x%2Bsqrt%289%29%2Asqrt%282%29-3%2Bsqrt%284x%5E2%29%2Asqrt%282%29
highlight%28x%2B3%2Asqrt%282%29-3%2B2x%2Asqrt%282%29%29 This has no like terms.
Happy Calculating!!!!
