Your answer should be a polynomial in standard form (3b – 4)(b + 2)

Just use the FOIL method. It's ok if you don't know what that is. IN other words, multiply all the terms together, and you should end up with 3b^2+6b-4b-8. simplify and you'll be left with 3b^2+2b-8. standard form is just in descending order of highest exponent to lowest. **Put the term without a variable last.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

=240

=48
