How do you factorize b² 8b 15?

Answer 1

To factorize something, you will need to break it up into two parts. The phrase (b+3)(b+5) when multiplied together will give b^2+8b+15. When factoring something that is in the second order, meaning a variable that is squared, the two factors always have 1 variable and 1 number that when multiplied equal the third part of the initial equation, and when added together, equal the coefficient of the second part of the equation.
