What is the solution to the equation?

Oxana [17]

ANSWER

EXPLANATION

The given equation is

$\frac{ - 3d}{ {d}^{2} - 2d - 8} + \frac{3}{d - 4} = \frac{ - 2}{d + 2}$

Factor the first fraction to get,

$\frac{ - 3d}{(d + 2)(d - 4)} + \frac{3}{d - 4} = \frac{ - 2}{d + 2}$

Multiply through by (d+2)(d-4)

$- 3d + 3(d + 2) = - 2(d - 4)$

Expand:

$- 3d + 3d + 6 = - 2d + 8$

$6 = - 2d + 8$

$6 - 8= - 2d$

$- 2 = - 2d$

divide both sides by -2

$d = 1$

Help with this question please

algol [13]

a) (f+g)(x)=6x^3-x^2+3x+4+8x^3-1

=14x^3-x^2+3x+3

b)(f+g)(2)=14(2)^2-4+6+3

=61

c)(f-g)(x)

=6x^3-x^2+3x+4-8x^3+1

= -2x^3-x^2+3x+5

d( (f-g)(-3)

= -2(-3)^3-(3)^2+9+5

=59
