Question

Find the zero of the polynomial p ( x) = 6xsquare+7x-3

Answer 1

Answer:

x = -3/2                          x = 1/3

Step-by-step explanation:

p(x) = 6x² + 7x - 3

Splitting middle terms

6x² + 9x - 2x -3                     [∵ 9×(-2) = -18 and 9 - 2 = 7]

taking 3x common from first two terms and -1 from last two terms

3x ( 2x + 3) -1 (2x + 3)

(2x + 3) ( 3x - 1)

To find zero

2x + 3 = 0                3x - 1 = 0

x = -3/2                          x = 1/3
