Which expression is equivalent to `\left(x+3\right)\left(x+5\right)`?

1 answer

The equivalent expression is `x^2 + 8x + 15`.

To get this expression, you first expand the given expression using the distributive property:

` (x+3)(x+5) = x*x + x*5 + 3*x + 3*5`
`= x^2 + 5x + 3x + 15`
`= x^2 + 8x + 15`.
