Question

factorise : 36 - 21x + 3x^2

Answer 1

Answer:

${\longrightarrow{\boxed{\rm{3(x - 3)(x - 4)}}}}$

Step-by-step explanation:

Given:-

$\longrightarrow\rm{36 - 21x+3x^{2}}$

ㅤ

Find:-

⇢ Factories the given expression.

ㅤ

Calculations:-

$\longrightarrow\rm{36 - 21x+3x^{2}}$

ㅤ

Now changing (3x²) on the other phase:

$\longrightarrow\rm{3x^{2} - 21x + 36}$

ㅤ

Required form:

${\longrightarrow{\boxed{\rm{3(x - 3)(x - 4)}}}}$

ㅤ

Therefore, this is the required answer.
