Question

-60a+6(a+5)^2= Помогите упростить..

Answer 1

$- 60a + 6 {(a + 5)}^{2} = - 60a + 6( {a}^{2} + 10a + 25) = \\ = - 60a + 6 {a}^{2} + 60a + 150 = 6 {a}^{2} + 150$

Answer 2

$- 60a + 6(a + 5) ^{2} = - 60a + 6( {a}^{2} + 10a + 25) = - 60a + 6 {a}^{2} + 60a + 150 = 6 {a}^{2} + 150 = 6( {a}^{2} + 25)$
я думаю что ответ надо оставить такой:
$6 {a}^{2} + 150$

Answer 3

To simplify the expression, we can start by expanding the square:

-60a + 6(a+5)(a+5)

Next, we can use the distributive property to multiply (a+5)(a+5):

-60a + 6(a^2 + 10a + 25)

Now we can simplify by combining like terms:

-60a + 6a^2 + 60a + 150

The -60a and +60a cancel each other out, leaving us with:

6a^2 + 150

Finally, we can factor out a 6 to simplify further:

6(a^2 + 25)

So the simplified expression is 6(a^2 + 25).
