Question

FACTORISE - ( a² + a + 2 ) ( a²- a + 2 )

Answer 1

( a² + a + 2 ) ( a² - a + 2 )

= let us see the equation through the formula of ( a + b ) ( a - b ) = a² - b²

= the value of a = a²

= the value of b = a + 2

therefore, the equation can further be solved as ==>

( a² + a + 2 ) ( a² - a + 2 ) = a² - ( a + 2 )²

Answer 2

Step-by-step explanation:

GIVEN ,

$({a}^{2} + a + 2)( {a}^{2} - a + 2)$

WE ARE GETTING THE IDENTITY BY SEEING THIS :

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

LET'S TAKE a=

${a}^{2}$

LET'S TAKE b=

$a + 2$

NOW LET'S solve IT.

${a}^{2} - ( {a + 2})^{2}$

SRY MATE YOUR QUESTION IS WRONG

WE DON'T HAVE TO FACTORISE IT WE JUST SIMPLIFY IT.

FACTORISATION:IT'S MEANS TO MAKE THE ALGEBRAIC EXPRESSION TO PRODUCT FORM..
