Question

simplify the following . ( a square + 1 - a ) ( a square - 1 + a ) . class 8 math solution​

Answer 1

Answer:

(a² + 1 - a )(a² -1 + a)

a²(a² - 1 +a) +1(a² - 1 +a) - a

Step-by-step explanation:

(a² - 1 +a)

a⁴ - a² +a³ +a²-1+a- a³+a- a²

a⁴ -a² +2a - 1

Answer 2

Answer:

$( {a}^{2} + 1 - a)( {a }^{2} - 1 + a) \\ = ( {a}^{2} + 1 - a)( {a}^{2} - (1 - a)) \\ = {( {(a)}^{2}) }^{2} - {(1 - a)}^{2} \\ = {a}^{4} - (1 - 2a + {a}^{2} ) \\ = {a}^{4} - 1 + 2a - {a}^{2}$
