A^2+10a+24 does anyone know how to do it
Komok [63]

Answer:

(a  + 4)(a + 6)

Step-by-step explanation:

f(a) = a² + 10a + 24

I think you are asking us to factor the quadratic.

1. Multiply the leading coefficient and the constant

1 × 24 = 24

2. Find two numbers that multiply to give 24 and add to give 10.

Possible pairs are 1, 24; 2, 12; 3, 8; 4, 6

Start with the numbers near the end of the list.

By trial and error, you will find that 4 and 6 work:

4 × 6 = 24 and 4 + 6 = 10

3. Rewrite 10a as 4a + 6a

a² +4a + 6a +24

4. Factor by grouping the first two and the last two terms

a(a + 4) + 6(a + 4)

5. Distribute the a + 4

(a  + 4)(a + 6)

a² + 10a + 24 = (a  + 4)(a + 6)

Which equation shows a valid, practical step in solving
lesantik [10]

For this case we have the following equation:

\sqrt [4] {2x-8} + \sqrt [4] {2x + 8} = 0

If we subtract both sides of the equation \sqrt [4] {2x + 8} we have:

\sqrt [4] {2x-8} = - \sqrt [4] {2x + 8}

To eliminate the radical we raise both sides of the equation to the fourth power:

(\sqrt [4] {2x-8}) ^ 4 = (- \sqrt [4] {2x + 8}) ^ 4

Answer:

Option D
