Factor 4x 2 + 12x + 5 . (2x + 5)(2x + 1)

Juliette [100K]

Factor
in form
ax²+bx+c form
use the ac method
1. mulitply a and c
2. factor the result such that the 2 factors add to b
3. split b into those 2 factors
4. group the terms
5. undistribute common factors
6. undistribute again

first multiply ac
4 times 5=20
now
what 2 numbers multiply to 20 and add to 12
2 and 10
4x²+2x+10x+5
group
(4x²+2x)+(10x+5)
undistribute
2x(2x+1)+5(2x+1)
undistribute the (2x+1)
(2x+1)(2x+5) is factored form whih you have there, nice

Please help me. alg 2<br><br> Find the common ratio of the geometric sequence -13, 39, -117

grandymaker [24]

Answer:

-3

Step-by-step explanation:

you can divide the second term by the first term to solve

39/-13 = -3

then, I like to check that this fits with the third term

39*-3 = -117

so the common ratio is -3

Direct Variation - Item 2845

Brums [2.3K]

The equation of direct proportion is y = 62x

<h3>Direct variation</h3>

Two quantities are said to vary directly proportional to each other when an increase in one leads to an increase in the other or a decrease in one leads to a decrease in the other.

Direct variation is given by:

y = kx

where y, x are the variables and k is the constant of proportionality.

The equation of direct proportion is y = 62x

The expression (4x+5)(3x-7) is the factorization of what trinomial?

RUDIKE [14]

It's easy to find the trinomial. Just multiply (4x + 5) and (3x - 7) together.

$(4x + 5)(3x - 7) = 12x^{2} - 28x + 15x - 35 = 12x^{2} - 13x - 35$

So the final answer is $12x^{2} - 13x - 35$
