Answer:


\boxed{ \boxed{ \bold{ {x}^(2) + 4x - 21}}}

Explanation:


\sf{(x - 3)(x + 7)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.


\sf{x(x + 7) - 3(x + 7)}


\sf{ {x}^(2) + 7x - 3x - 21}

Collect like terms


\sf{ {x}^(2) + 4x - 21}

Hope I helped!

Best regards!!
