Answer:
To show how x² + 6x + 5 is equivalent to (x + 5)(x + 1), we can use the FOIL method, which stands for First, Outer, Inner, and Last.
First, we multiply the first term of each factor: x and x, which gives x².
Next, we multiply the outer terms of each factor: x and 1, which gives x.
Then, we multiply the inner terms of each factor: 5 and x, which gives 5x.
Finally, we multiply the last term of each factor: 5 and 1, which gives 5.
Adding up these terms, we get:
x² + x + 5x + 5
Simplifying by combining like terms, we get:
x² + 6x + 5
This is the same as the original expression. Therefore, we have shown that:
x² + 6x + 5 = (x + 5)(x + 1)
