Please please can you help me understand how to rearrange this formula to make b the subject:
abc/3=c^2+a(b+2)
abc/3=c^2+a(b+2)
Prove It said:Start by expanding the brackets, moving every term that has a "b" to one side, and taking b out as a factor.
sarannie said:Thank you, I have an absolute mental block with algebra.
So do I do a x b a x 2 next?
Rearranging the subject of an equation involves isolating the variable you want to solve for on one side of the equation. This can be done by using inverse operations, such as addition, subtraction, multiplication, and division, to move all other terms to the other side of the equation.
Rearranging the subject of an equation allows us to solve for a specific variable, which is often necessary in solving real-world problems. It also helps us better understand the relationship between different variables in an equation.
Some common mistakes include forgetting to perform the same operation on both sides of the equation, incorrectly distributing a negative sign, and forgetting to change the sign of a term when moving it across the equal sign.
There are no shortcuts for rearranging the subject of an equation, but there are some tips that can make the process easier. These include keeping track of the operations performed on each side of the equation and checking your work by plugging the solution back into the original equation.
In most cases, yes, you can rearrange the subject of an equation. However, there are some equations, such as those involving radicals or logarithms, where rearranging the subject may not be possible. It is important to understand the restrictions of the equations and use appropriate methods to solve them.
