Question

factorise (x² +4)-2a-a²-5
​

Answer 1

➸ Given:-

• (x²+4)-2a-a²-5

☣ To Do:-

• Factorisation.

☢ Solution:-

$→\;({x}^{2} + 4) - 2a + {a}^{2} - 5 \\ →\; {x}^{2} + 4 - 2a + {a}^{2} - 5 \\ →\;{x}^{2} - 2a + {a}^{2} - 1 \\ →\; {x}^{2} - ( {a}^{2} + 2a + 1) \\ →\; {x}^{2} - ( {a}^{2} + 2a + {1}^{2} ) \\→\; {x}^{2} - {(a + 1)}^{2} \\➝\; (x + (a + 1))(x - (a + 1))$

• $\green{\bold{[x+(a+1)][x-(a+1)]}}$
