Answer:
-3( 5u - 2v -1 ) = -15u + 6v + 3
Explanation:
Distributive property:
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
A (B +C + D ) = A×B + A×C + A×D
For example 2(x+y)=2x+2y
Given:
-3( 5u - 2v -1 )
To Remove:
Parenthesis
Solution:
Parenthesis = Brackets
By applying Distributive property to the given equation we get
-3( 5u - 2v -1 ) = -3×5u - -3×2v - -3×1
-3( 5u - 2v -1 ) = -15u + 6v +3
∴ -3( 5u - 2v -1 ) = -15u + 6v +3 ............Required answer
