SOLUTION

TO DETERMINE

The equation that formed by cubing each root of equation

 \sf{ {x}^{2}  - 5x + 6 = 0}

EVALUATION

First we find the roots of the given Quadratic equation

 \sf{ {x}^{2}  - 5x + 6 = 0}

 \sf{ \implies {x}^{2}  -(3 + 2)x + 6 = 0}

 \sf{ \implies {x}^{2}  -3x - 2x + 6 = 0}

 \sf{ \implies x(x - 3) - 2(x - 3)= 0}

 \sf{ \implies (x - 3) (x - 2)= 0}

 \sf{ either \:  \:  (x - 3)  = 0 \:  \: or \:  \: (x - 2)= 0}

Now

 \sf{ (x - 3)  = 0 \:  \: gives \:  \:x = 3}

 \sf{ (x - 2)  = 0 \:  \: gives \:  \:x = 2}

So the roots of the given Quadratic equation is 3 and 2

Now we have to find the equation that formed by cubing each root of the given equation

So the roots of the required equation are 27 and 8

So the required Quadratic equation is

 \sf{ {x}^{2} - (27 + 8)x + (27 \times 8) = 0 }

 \sf{ \implies {x}^{2} - 35x + 216 = 0 }
