Question

if x=4.5 then the value of √9x²-6x+1+3x is​

Answer 1

Answer: 9X^2 - 6X + 1

9X^2 -3X-3X +1

3X (3X- 1)-1 ( 3X - 1)

(3X-1)(3X-1)

X = 1/3; X = 1/3

Step-by-step explanation:9x² - 6x + 1

9x² - 3x - 3x + 1

3x ( 3x - 1 ) -1 ( 3x - 1 )

( 3x - 1 ) ( 3x - 1 )

Answer 2

Answer:

Given - X = 4.5

To find - value of √9x²-6x+1+3x

solution -

putting the value of X in eq.

√9( 4.5) (4.5) -6(4.5) +1+3(4.5)

3( 20.25) - 2.7 + 1 + 13.5

60.75 - 2.7 + 1 + 13.5

60.75 -11.8

48.95
