Question

( left(x^{2}+x-2right)left(x^{2}-x+2right) )
( left(x^{2}+(x-2)right)left(x^{2}-(x-2)right. )
( (a+b)(a-b)=a^{2}-b^{2} )
( x^{4}-(x-2)^{2} )
( x^{4}-left(x^{2}+4-4 xright) )
( x^{4}-x^{2}+4 x-4 )

# the area of the rectangle. 14. Using suitable identities, find the product of (x2 + x - 2)(x2 - x + 2).
