Question

es. 23 The zeroes of polynomial x2-x-6 is​

Answer 1

Answer:

Given polynomial :

${x}^{2} - x - 6$

Solution :

${x}^{2} - x - 6 = 0$

${x}^{2} - (3 - 2)x - 6 = 0$

${x}^{2} - 3x + 2x - 6 = 0$

$x(x - 3) + 2(x - 3) = 0$

$(x - 3)(x + 2) = 0$

$(x - 3) = 0 \: and \: (x + 2) = 0$

$x = 3 \: and \: x = - 2$

So, 3 and -2 are the zeros of the polynomial.

Ans. 3, -2

Hope it helps.

Answer 2

Answer:

x^2-3x+2x-6

x(x-3) +2(x-3)

(x-3) (x+2)

x=3

x=-2
