Question

(5y-2x)*(5y+x)=................​

Answer 1

Ответ:

(5у-2х)*(5у+х)=25у²-5ху-2х².

Answer 2

To expand the expression (5y - 2x)(5y + x), you can use the distributive property (FOIL) or the distributive law.

(5y - 2x)(5y + x) = 5y * 5y + 5y * x - 2x * 5y - 2x * x

Now, multiply each pair of terms:

25y^2 + 5xy - 10xy - 2x^2

Combine like terms:

25y^2 - 5xy - 2x^2

So, the expanded expression is 25y^2 - 5xy - 2x^2.
