Question

If theta and beta are the roots of the quadratic equation X square - 4 x minus 6 is equal to zero find the value of theta square + beta square and theta Cube + beta cube

Answer 1

Answer:

x²-36x-729=0

Step-by-step explanation:

the equation is

x²+6x-4=0

1st we shall find the value of roots alpha and beta

then

Alpha=-3+√13

Beta=-3-√13

after it we shall find the equation whose roots are

(-3+√13)&(-3-√13)

thus in the end we get the quadratic equation

x²-36x-729=0
