If one zero of the polynomial (a^2+9)x^2+13x+6a is the reciprocal of the other, find the value of a.

mihalych1998 [28]

Answer: a^2x^2+9x^2+13x+6a

Step-by-step explanation:

(a^2+9) x^2+ 13x +6a

x^2(a^2+9)+13x+6a

Expand:x^2(a^2+9): a^2 x^2+9^2

x^2 a^2 +x^2*9

a^2 x^2+9x^2

a^2 x^2+9x^2+13x+6a

-4x+y=23 and 4x-9y=-15

astra-53 [7]

Answer: x= -6; y= -1

Step-by-step explanation:

-4x + y = 23

4x - 9y = - 15

-4x + y = 23

y = 23 + 4x [Add 4x to both side]

4x - 9(23 + 4x) = - 15

4x - 207 - 36x = - 15

-32x - 207 = -15

-32x = 192 [Add 207 to both side]

x = -6 [Divide -32 from both side]

-4x + y = 23

-4(-6) + y = 23 [Plug in -6 for x]

24 + y = 23 [Subtract 24 from both side]

y = -1

Factor the expression below using the greatest common factor 6p3- 2p2 - 8p

miss Akunina [59]

Answer:

The Factor of expression using the greatest common factor is $2p(3p^2- p-4)$

Step-by-step explanation:

Consider the provide expression.

$6p^3- 2p^2 - 8p$

We need to Factor the expression using the greatest common factor.

First look at the coefficients of the variable.

The coefficients are the factor of 2.

Variable p is the greatest common factor in the provided expression.

$2p\times 3p^2- 2p\times p- 2p\times 4$

$2p(3p^2- p-4)$

Hence, the Factor of expression using the greatest common factor is $2p(3p^2- p-4)$ .

Given the following formula, solve for I. P = 2(1 + b)

patriot [66]

Answer: $l=\dfrac{P}{2}-b$

Step-by-step explanation:

P = 2(l + b)

Divide both sides by 2:

$\dfrac{P}{2}=l+b$

Subtract b from both sides:

$\dfrac{P}{2}-b=l$

Note: You can also multiply b by $\frac{2}{2}$ if you want the left side to be one fraction.

$\dfrac{P}{2}-\bigg(\dfrac{2}{2}\bigg)b=l\\\\\\\dfrac{P-2b}{2}=l$
