Very easy math question!?

Question

(x-5y)^2

I got

-4y^2

Just wanted to make sure i am right

Answer 1

(x-5y)^2 is
x^2+25y^2-10xy

When you have 2 variables in one equation and have square it then we use the formula
(a-b)^2=a^2 + b^2 - 2ab

Answer 2

pls explain how you get the reasult.
Does not make any sense

squaring is pretty straightforward: multiply by itself

(x-5y) (x-5y)= x^2-10xy +25y^2

Answer 3

What are you wanting to do with (x-5y)^2 so that you end up with -4y^2?

Your question doesn't make sense.

Answer 4

sorry man ur answer is not right

(x-5y)(x-5y) = x^2 - 10xy + 25 y^2

Answer 5

x^2 - 10xy + 25y^2

sorry man

try foiling (x-5y)(x-5y)
that is, First times first, outer times outer, inner times inner, last times last, and add these together

Answer 6

What is the question? Where did you get -4y^2 from. What is -4y^2 equal to? Listen to Gino R

Answer 7

if you want (x-5y)^2=?
the answer is x^2+25y^2-10xy
1)the answer can't be negative.
2)the answer should have a factor of x^2 too.
(x-5y)(x-5y)=
1)x*x=x^2
+
2)x*(-5y)=-5xy
+

3)(-5y)*x=-5xy
+
4)(-5y)*(-5y)=25y^2
==>x^2-10xy+25y^2

Answer 8

no,you are not right

x^2-10xy+25y^2

when you square you doubled the middle term and square the 2 outer terms

Answer 9

You need to multiple each part of the sum by x and then by 5y and add them up.
= x squared -5xy -5xy +25y squared or x squared - 10xy + 25y squared

Answer 10

No sir, you are wrong. The correct answer is

x^2 - 19xy + 25y^2
