Question

x^2+48x-324=0 solve for x

Answer 1

Heya User,

--> x²  + 48x - 324 = 0
=> x² + 54x - 6x - 324 = 0
=> x[ x + 54 ] - 6[ x + 54 ] = 0
=> [ x - 6 ][ x + 54 ] = 0
=> [ x - 6 ] = 0 ------------- or --------------- [ x + 54 ] = 0
=> x = 6, -54 ; <--- Ans....

Answer 2

The value of x is "6 or -54".

Step-by-step explanation:

We have,

$x^{2} +48x-324=0$

To find, the value of x = ?

$x^{2} +48x-324=0$

By factorisation method,

$x^{2} +54x-6x-324=0$

x(x+54)-6(x+54)=0

⇒ $(x-6)(x+54)=0$

⇒ $(x-6)=0 or (x+54)=0$

⇒$x-6=0$

∴ $x=6$

$x+54=0$

∴$x=-54$

∴ x = 6 or - 54

Hence, the value of x is 6 or -54.
