The value of 2x (-3x) isa)5x2b)-6xc)-5x2d)-6x2Correct answer is option...
Solution:
The given expression is 2x(-3x).
We can simplify this expression using the distributive property of multiplication over addition or subtraction:
2x(-3x) = (2x)(-3x) = 2*(-3)*x*x = -6x^2
Therefore, the value of 2x(-3x) is -6x^2.
Explanation:
Distributive property of multiplication over addition or subtraction is a property of arithmetic that is used to simplify expressions. This property states that the product of a number and the sum or difference of two or more numbers is equal to the sum or difference of the products of the number and each of the numbers in the sum or difference.
In the given expression, we have to multiply 2x and -3x. Using the distributive property, we can write this expression as:
2x(-3x) = 2x*(-3)*x
Now, we can multiply 2, -3, and x to get:
2*(-3)*x*x = -6x^2
Therefore, the value of 2x(-3x) is -6x^2.
Final Answer: The correct answer is option 'D' which is -6x^2.
