anyone can give example on this i would be very happy :)
You have the expression 5a^2 - 20ax
So first you have to find the Greatest common factor (GCF)
which in this case is 5a.
So you put the GCF at the front and you open brackets:
5a(a-4x)
why dont u take the common terms in common
5a^2 - 20ax
5a(a - 4x)
x^4 - 256 distinction of two squares: (a + b)(a - b) = a^2 - ab + ab - b^2 = a^2 - b^2 sort of a^2 - b^2 aspects into (a + b)(a - b) here a = x^2, b = sixteen (x^4 - 256) = (x^2 + sixteen)(x^2 - sixteen) = (x^2 + sixteen)(x + 4)(x - 4)
