Factor (x-1)^3 (4x-9) - (16x+9) (x+1)^2 ? Please explain steps, I'm stuck !
Lapatulllka [165]

(x-1)^3 (4x-9) - (16x+9) (x+1)^2

= (x^3-3x^2+3x-1) (4x-9) - (16x+9) (x^2+2x+1)

= (4x^4-12x^3+12x^2-4x-9x^3-27x^2-27x+9)-(16x^3+32x^2+16x+9x^2+18x+9)

= (4x^4-21x^3+39x^2-31x+9)-16x^3-32x^2-16x-9x^2-18x-9

= 4x^4-21x^3+39x^2-31x+9-16x^3-32x^2-16x-9x^2-18x-9

= 4x^4-37x^3-2x^2-65x

= x(4x^3-37x^2-2x-65)

hence final factor is x(4x^3-37x^2-2x-65)

hiroto solved the equation 6 – 4|2x – 8| = –10 for one solution. his work is shown below. 6 – 4|2x – 8| = –10 –4|2x – 8| = –16 |
fenix001 [56]

Answer:

 x=2 is the other solution.

Step-by-step explanation:

We have been given the equation:  6-4|2x-8|= -10

we will do it by collecting the like terms so the equation will become by shifting 6 on right hand side

-4|2x-8|= -10-6

After simplifying it in first step

-4|2x-8|= -16

We will define the modulus function which is:

|x|=x or -x

So we will consider the negative case

-4(-)(2x-8)=-16

8x-32= -16

8x= -16+32

8x=16

x=2 is the other solution
