Question

Find the value of 6m2 – 3 m +4 when m= 2​

Answer 1

• As per the data given in the question, we have to find the value of the expression.

            Given data:- $m=2$

            To find:- Value of the expression $6m2-3m+4.$

            Solution:-

• To solve the above equation we will follow the BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

          where,

        $\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

          Therefore,

        $6m2-3m+4\\=(6)(2)(2)-(3)(2)+4 \\=(12)(2)-(3)(2)+4 \\=24-(3)(2)+4 \\=24-6+4 \\=18+4 \\=22$

      Hence we will get the value $22.$

Answer 2

From the data given in the question,

We have to find the value of the expression.

From the data,

It is given that,

$6m^2-3m+4$

Here, we have to find the value of the expression when the value of m = 2

For finding the value of the expression we will put 2 in place of m and determine the value of obtained expression by using BODMAS.

As we know that,

As per BODMAS rule,

We have,  

$\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

Therefore the value of the expression will be,

$6m^2-3m+4\\=(6)(2)(2)-(3)(2)+4 \\=(12)(2)-(3)(2)+4 \\=24-(3)(2)+4 \\=24-6+4 \\=18+4 \\=22$

Hence we will get the value of the expression as 22.
