To solve the equation 2x² - 11x + 15 = 0 by factoring, we need to find two numbers that multiply to 2*15=30 and add up to -11.
The numbers are -6 and -5.
Therefore, the factored form of the equation is: (2x - 5)(x - 3) = 0
Setting each factor to zero:
2x - 5 = 0
2x = 5
x = 5/2
x - 3 = 0
x = 3
So the solutions to the equation are x = 5/2 and x = 3. Answer: x = 5/2, x = 3.
The numbers are -6 and -5.
