Answer:
A. 48r² - 10r + 3
Step-by-step explanation:
Solve (6r - 1) × (-8r - 3)
1. Distribute 6r and -1 (into -8r - 3):
-48r² - 18r + 8r + 3
2. Combine like terms (-18r and 8r):
-48r² - 10r + 3
So, your answer is -48r² - 10r + 3
The answer is 1 _ (-48r²-10r+3)
What is BODMAS?
BODMAS stands for (Brackets, of(which means multiplication), Division, multiplication, addition, subtraction) and this is followed in the same order where brackets are the priority and subtraction the least.
How to multiply Variables?
To multiply variables you have to use BODMAS and properties like commutative, and associative. For example (ax+by)(bx+ay) you can write it as ax(bx+ay)+by(bx+ay) and now you can multiply.
How to solve the given problem?
(6r-1)(-8r-3) = 6r(-8r-3) -1(-8r-3)
6r(-8r-3) -1(-8r-3) = -48r² - 18r + 8r + 3 (We have used properties of integers which is -1×-1 = 1 and -1×1 = -1)
So hence (6r-1)(-8r-3) = -48r²-10r+3
The answer to the problem is option 1 -48r²-10r+3
