Question

find the value of x for given. equation 4x2 -12x +9=0 ​

Answer 1

$\large{\underline{\sf{Answer:-}}}$

= 4x² - 13x + 9 = 0

= 4x² - 4x - 9x + 9 = 0

= 4x( x - 1) - 9( x - 1) = 0

= ( x - 1) ( 4x - 9) = 0

Now we have,

• = x - 1 = 0
• = x = 1

And also,

• = 4x - 9 = 0
• = 4x = 9
• = x = $\dfrac{9}{4}$

•°• The value of x is 1 and 9/4.
