List the factor pairs of ac for the trinomial 12x^2-5x-2.

yKpoI14uk [10]

Answer:

(3x - 2) (4x + 1)

Step-by-step explanation:

12x² - 5x - 2

Since the first term has a coefficient, you need to multiply -2 with 12 to get -24.

Two factors that add up to -5 and have a product of -24 are -8 and 3.

12x² - 8x + 3x - 2

Rearrange the expression to find the GCF.

12x² + 3x - 8x - 2

3x (4x + 1) + (-1)2(-4x -1)

3x (4x + 1) - 2 (4x + 1)

(3x - 2) (4x + 1)

The given two-parameter family is a solution of the indicated differential equation on the interval (−∞, ∞). Determine whether a

SVEN [57.7K]

We're told that the ODE

$x^2y''-5xy'+8y=24$

has solution

$y=C_1x^2+C_2x^4+3$

a. If $y(-1)=0$ and $y(1)=8$ , then

$\begin{cases}0=C_1+C_2+3\\8=C_1+C_2+3\end{cases}$

but there is no solution to this system, so a member cannot be found.

b. If $y(0)=8$ and $y(1)=5$ , then

$\begin{cases}8=3\\5=C_1+C_2+3\end{cases}$

but the first equation is obviously false, so a member cannot be found.

c. If $y(0)=3$ and $y(1)=0$ , then

$\begin{cases}3=3\\0=C_1+C_2+3\end{cases}$

which has infinitely many solutions for $C_1,C_2$ , so a member can be found.

d. If $y(1)=3$ and $y(2)=15$ , then

$\begin{cases}3=C_1+C_2+3\\15=4C_1+256C_2+3\end{cases}\implies C_1=-\dfrac5{84},C_2=\dfrac5{84}$

so a member can be found.
