Question

how to factorise (2x+5y-2z)²

Answer 1

(2x+5y-2z)²

(2x)²+(5y)²+(2z)²-2(2x+5y-2z)

4x²+25y²+4z²-4x+10y-4z answer

Answer 2

HEYA USER !!

HERE IS UR ANSWER ---

FACTORISE ::

$(2x+5y-2z)^{2}$

Put this in the formula of $(a + b + c)^{2}$

And that is (a^2 + b^2 + c^2 + 2ab + 2bc + 2ca)

[(2x)^2+(5y)^2+(-2z)^2+2*2x*5y+2*5y*(-2z)+2*(-2z)*2x]

4x^2+25y^2+4z^2+20xy+(-20yz)+(-8xz)

4x^2+25y^2+4z^2+20xy-20yz-8xz

HOPE IT HELPS !!!
