Question

(2x+1)(x+1) help)))))

Answer 1

Ответ:

(2x+1)(x+1)=2x^2+2x+x+1=2x^2+3x+1

Answer 2

Certainly! To simplify the expression (2x+1)(x+1), you can use the distributive property, also known as the FOIL method (First, Outer, Inner, Last). Here's how you can do it step by step:

1. Multiply the first terms in each binomial: (2x) * (x) = 2x^2

2. Multiply the outer terms in each binomial: (2x) * (1) = 2x

3. Multiply the inner terms in each binomial: (1) * (x) = x

4. Multiply the last terms in each binomial: (1) * (1) = 1

Now, combine these results together:

(2x^2) + (2x) + (x) + (1)

Next, combine like terms:

2x^2 + 3x + 1

So, the simplified expression is:

2x^2 + 3x + 1
