Let a,b,,c and x elements in the group G. In each of the following solve for x in terms of a,b,c, and c.
Alchen [17]

Answer with Step-by-step explanation:

We are  given that  a, b, c and x are elements in the group G.

We have to find the value of x in terms of a, b and c.

a.x^2a=bxc^{-1}

x^2ac=bxc^{-1}c=bx

x^{-1}x^2ac=x^{-1}bx=b (x^{-1}bx=b)

xac=b

xacc^{-1}=bc^{-1}

xa=bc^{-1}    (cc^{-1}=)

xaa^{-1}=bc^{-1}a^{-1}

x=bc^{-1}a^{-1}

b.acx=xac

acxc^{-1}=xacc^{-1}=xa  (cc^{-1}=1,cxc^{-1}=x)

axa^{-1}=xaa^{-1}  (aa^{-1}=1,axa^{-1}=x)

x=x

Identity equation

Hence, given equation has infinite solution and satisfied for all values of a and c.

Drag the correct factors to the expression. Not all factors will be used. Use synthetic division to find all the factors of this
fiasKO [112]

The factors are therefore;  (4x – 3), (x + 3) and (x – 1)

<h3>What is a polynomial?</h3>

A polynomial is is a function that contains an algebraic term which is raised to a particular power.

  • If it is raised to power 1 it is linear
  • If it is raised to power 2 it is quadratic
  • If its is raised to power 3 it is cubic
  • If it i raised to power 3 it is quartic

Now we have;

4x³ + 5x² – 18x + 9

Thus we can write;

4x³ – 3x² + 8x² – 6x – 12x + 9

Using the factors;

x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)

Therefore;

(4x – 3)(x² + 2x– 3)

(4x – 3)(x² + 3x – x – 3)

(4x – 3)(x + 3)(x – 1)

The factors are therefore;  (4x – 3), (x + 3) and (x – 1)
