Question

4. Find the roots of the polynomial equations .
(i) 5x – 6 = 0 (ii) x +3 = 0
(iii) 10x + 9 = 0 (iv) 9x – 4 = 0

Answer 1

HELLO DEAR,

( 1 ). 5x - 6 = 0

x = 6/5

( 2 ). x + 3 = 0

x = -3

( 3 ). 10x + 9 = 0

x = -9/10

( 4 ). 9x - 4 = 0

x = 4/9


I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

(i) :

5x – 6 = 0

$5x = 6 \\ \\ x = \frac{6}{5}$

(ii) :

x + 3 = 0

x = –3


(iii) :

10x + 9 = 0

10x = –9

$x = - \frac{9}{10}$


(iv) :

9x –4 = 0

9x = 4

$x = \frac{4}{9}$
