Question

solve the problem
(2x) + (5) + ( - 5)×(2x)+(5)+(−5)​

Answer 1

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

: $\implies$ (2x + 5) (2x − 5)

: $\implies$ (2x)² - 5²

: $\implies$ 4x² - 25

Answer 2

Answer:

4x^2

it is a property of (a+b+c)^2

Explanation:

{2x+5-5}*{2x+5-5}

(a+b-c)^2=a^2+b^2+c^2+2(ab-bc-ca)

(2x)^2+5^2+5^2 + 2(2x*5-5*5-5*2x)

=4x^2+25+25+2(10x-25-10x)

= 4x^2+50+ 2*-25

=4x^2+50+(-50)

= 4x^2
