Question

[x²-16x+63=0] X?? X value what is x value

Answer 1

Heya !!




X² - 16X + 63 = 0




X² - 9X - 7X + 63 = 0




X ( X - 9 ) -7 ( X - 9 ) = 0




( X - 9 ) ( X - 7 ) = 0




( X - 9 ) = 0 OR ( X - 7 ) = 0



X = 9 OR X = 7.

Answer 2

Given: The equation is$[x^2-16x+63=0]$.

We have to find the value of$x$.

We are solving in the following way:

We have,

$[x^2-16x+63=0]$

As we know that ${9\times7=63}$and$9+7=16$.

So, we can write the above equation as:

$=>x^2-9x-7x+63\\=>x(x-9)-7(x-9)\\=>(x-7)(x-9)$

Solving the above equation further we get,

$=>x-7=0\ ;\ x-9=0\\=>x=7\ ;\ x=9$

Hence, the value of$x$ is$7 \ or\ 9$.
