Simplify the expression. x2 + x - 6 /x2 - 4 · x2 - 9/ x2 + 6x + 9

Agata [3.3K]

we are given

$\frac{(x^2+x-6)}{(x^2-4)}*\frac{(x^2-9)}{(x^2+6x+9)}$

step-1: Factor terms

$x^2+x-6=(x+3)(x-2)$

$x^2+6x+9=(x+3)^2$

$x^2-4=(x-2)(x+2)$

now, we can plug these values

and we get

= $\frac{(x+3)(x-2)}{(x-2)(x+2)}*\frac{(x-3)(x+3)}{(x+3)^2}$

step-2: Cancel common terms

we get

= $\frac{(x+3)}{(x+2)}*\frac{(x-3)}{(x+3)}$

we can again cancel numerator and denominator

and we get

= $\frac{(x-3)}{(x+2)}$ .............Answer

If p-1/p = 4 Find (p+1/p)²

DiKsa [7]

Answer:

Step-by-step explanation:

$\frac{p - 1}{p} = 4$

Solve for p.

The numerator. difference has to be 4 times the answer of the denomiator.

So we can say

$p - 1 = 4p$

Solve for p

$- 1 = 3p$

$p = - \frac{1}{3}$

Now plug this in for the other formula.

$( \frac{ - \frac{1}{3} +1}{ \frac{1}{3} } ) {}^{2} = 2 {}^{2} = 4$

The green dots must make up a triangle 1/3 of the original picture PLZ HELP

omeli [17]

Consider Point P to be (0,0) count the grid lines to find the location of points A, B and C

A=. (-6,-3)

B = (-9,6)

C =(3,9)

Now the scale is 1/3. So divide all the points by 3 to get the new location and place the green dots on them:

A’=(-2,-1)

B’ =(-3,2)

C’ =(1,3)
