To factor the expression (5x^2 + 8x - 21), we look for two numbers that multiply to (5 \times -21 = -105) and add to (8). These numbers are (15) and (-7). We can then rewrite the expression as (5x^2 + 15x - 7x - 21) and factor by grouping: (5x(x + 3) - 7(x + 3)). Thus, the factored form is ((5x - 7)(x + 3)).
