This is an expression you really don't "solve" expressions but you can certainly simplify it by perfoming the indicated multiplication.
%282a%2B3b%29%5E3+=+%282a%2B3b%29%282a%2B3b%29%282a%2B3b%29 Multiply the first pair of parentheses using the FOIL technique.
%282a%2B3b%29%282a%2B3b%29+=+4a%5E2+%2B+6ab+%2B+6ab+%2B+9b%5E2 Simplify.
4a%5E2+%2B+12ab+%2B+9b%5E2 Now multiply this by the third parentheses.
%284a%5E2+%2B+12ab+%2B+9b%5E2%29%282a+%2B+3b%29+=+8a%5E3+%2B+24a%5E2b+%2B+18ab%5E2+%2B+12a%5E2b+%2B+36ab%5E2+%2B+27b%5E3 Now simplify this.
8a%5E3+%2B+36a%5E2b+%2B54ab%5E2+%2B+27b%5E3
