Question

(2c-x)*(2c-5x) сколько будет?

Answer 1

(2c-x)(2c-5x)= 4c²-10xc-2xc+5c²= 4c²-12xc+5c²

Answer 2

To solve the expression (2c-x)(2c-5x), you can use the distributive property of multiplication over addition/subtraction, which states that a(b+c) is equal to ab + ac. Let's apply this property to the given expression:

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

Now, simplify each term:

= 4c^2 - 10cx - 2cx + 5x^2

Combine like terms:

= 4c^2 - 12cx + 5x^2

So, the simplified expression for (2c-x)*(2c-5x) is 4c^2 - 12cx + 5x^2.
