a2-2b2

24-x2

Answer 1

$<var>1-256v^8 = 1 -(16v^4)^2 = (1 + 16v^4)(1-16v^4) = </var>$ $<var>(1+16v^4) (1 - (4v^2)^2)= (1 + 16v^4)(1 + 4v^2)(1-4v^2) </var>$

 

= $<var>(1 + 16v^4)(1 + 4v^2) (1- (2v)^2) =(1 + 16v^4)(1 + 4v^2) (1+2v)(1-2v)</var>$

 

2) $<var>x^6 +7x -8 = (x-1) (x^5 +x^4 +x^3 +x^2 +x + 8 )</var>$

 

3) $<var>x^2 -3 = x^2 - (\sqrt{3})^2 = (x +\sqrt{3}) (x -\sqrt{3}) = -(\sqrt{3} + x) (\sqrt{3}-x)</var>$

 

4) $<var>5y^2 - 1 = (\sqrt{5}y)^2 - (1)^2= (\sqrt{5}y +1)(\sqrt{5}y-1)</var>$

 

5) $<var>a^2 -2b^2 = a^2 -(\sqrt{2}b)^2 = (a +\sqrt{2}) ( a -\sqrt{2})</var>$
