Question

(2u+3)(2u+5) help
and please show step by step​

Answer 1

Answer:

4u^2 + 16u + 15

Step-by-step explanation:

Multiply each of the terms in the first binomial by each of the terms of the second binomial (4 multiplications in all).

(2u + 3)(2u + 5) = (2u)(2u + 5) + 3(2u + 5)

= (2u)(2u) + (2u)(5) + 3(2u) + 3(5)

= 4u^2 + 10u + 6u + 15

= 4u^2 + 16u + 15

Answer 2

Answer:

16u²+15

Step-by-step explanation:

You will use the equation in the first bracket to multiply both of the equations. You'll have

2u(2u+3)+3(2u+5)

4u²+6u+6u+15

4u²+12u+15

16u²+15

That will be your final answer.
