-1
It is: x(x-3) factorized
x(x-7)
X2 - 4= (x + 2)(x - 2)===========
x times x times x times x times x times x = x6
What about it? Factorise it?
x + x = x(1+1)
It is: x(x-3) factorized
It could be x(1 -1) when factorised
x(x - 7)
( x - 14 ) ( x + 14 )
x(x+5)
x(x-7)
7x-x2 = x(7-x)
X(X2 - X)
-47
x2 + 4x = x(x + 4)
X=5
