Question

Find all the xeros of quadratic polynomial i) x2+1/6x -2

Answer 1

Answer:

4/3 and -3/2

Step-by-step explanation:

x^2 + 1/6x - 2

Taking 1/6 as common to make the quadratic polynomial more convenient

to be factorized

1/6 ( 6x^2 + x - 12 )

FACTORISING:--

1/6 ( 6x^2 - 8x + 9x- 12 )

1/6[2x (3x - 4) + 3 (3x - 4)]

1/6(2x + 3)(3x - 4)

So, x = -3/2 or x = 4/3

So, -3/2 and 4/3 are zeroes/roots of the polynomial.
