Question

Factorise 150 - 6 x square

Answer 1

Hi
Tell me the proper we

Answer 2

Answer:

$\large\bold\red{6(5 + x)(5 - x)}$

Step-by-step explanation:

We have to factorise ,

$150 - 6 {x}^{2}$

Further ,

Taking common term and simplifying,

We get,

$= 6(25 - {x}^{2} ) \\ \\ = 6( {5}^{2} - {x}^{2} )$

But,

We know that,

• ${a}^{2} - {b}^{2} = (a - b)(a + b)$

Therefore,

We get,

$= 6(5 + x)(5 - x)$
