please answer fast it's urgent ​

Answer 1

Answer:

its 4a2+15a

Step-by-step explanation:

Let's simplify step-by-step.

5a2−6a(a−2)+a(3+5a)

Distribute:

=5a2+−6a2+12a+(a)(3)+(a)(5a)

=5a2+−6a2+12a+3a+5a2

Combine Like Terms:

=5a2+−6a2+12a+3a+5a2

=(5a2+−6a2+5a2)+(12a+3a)

=4a2+15a

Answer 2

EXPLANATION.

Simplify :

⇒ 5a² - 6a(a - 2) + a(3 + 5a).

As we know that,

We can write equation as,

⇒ 5a² - (6a² - 12a) + (3a + 5a²).

⇒ 5a² - 6a² + 12a + 3a + 5a².

⇒ 5a² + 5a² - 6a² + 12a + 3a.

⇒ 10a² - 6a² + 15a.

⇒ 4a² + 15a.

⇒ a(4a + 15).
