Question

(6x+1)(1−3x)
I did 3 strategies but they all ended up with 6x-17x^2-3x

Answer 1

-18x²+3x+1

Explanation:

To do this, we need to multiply 6x+1 by 1 and then 6x+1 by -3x:

(6x+1)(1)+(6x+1)(-3x)

Let's first do...

(6x+1)(1)

Distribute 1 to both of the terms inside of the parentheses:

6x(1)+1(1)

6x+1

Then...

(6x+1)(-3x)

Distribute the -3x to both of the terms inside of the parentheses:

6x(-3x)+1(-3x)

-18x²-3x

Then we add them together:

-18x²-3x+6x+1

-18x²+3x+1
