Answer 1

x*3x+x*7+3*3x-3*7 перемножаешь и получаешь ответ

Answer 2

To multiply the two binomials $(x + 3)$ and $(3x - 7)$, you can use the distributive property (also known as the FOIL method). FOIL stands for First, Outer, Inner, Last. Let's go through the steps:

$(x + 3)(3x - 7)$

First: Multiply the first terms of each binomial. $x \cdot 3x = 3x^2$

Outer: Multiply the outer terms of each binomial. $x \cdot (-7) = -7x$

Inner: Multiply the inner terms of each binomial. $3 \cdot 3x = 9x$

Last: Multiply the last terms of each binomial. $3 \cdot (-7) = -21$

Now, add all these results together:

$3x^2 - 7x + 9x - 21$

Combine the like terms: $3x^2 + 2x - 21$

So, $(x + 3)(3x - 7) = 3x^2 + 2x - 21$.
