Question

Simplify completely.a.4x212 xwhen x +0.b. (2t)(3t)(t)c. (3x² - 4x +8)+(x² +6x-11)d. (3x² + 4x – 8) - (x² + 6x +11)

Answer 1

The expression in 4a) is given below

`(4x^2)/(12x)`

Collecting similar terms using the division rule of indices, we will have

`(a^m)/(a^n)=a^(m-n)`

The above expression therefore becomes

`\begin{gathered} (4x^2)/(12x) \\ =(4x^2)/(12x^1) \\ =(1)/(3)* x^(2-1) \\ =(1)/(3)* x \\ =(x)/(3) \end{gathered}`

Hence,

The final answer = x/3
