Question

simplify 3p (4p-5) +3 and find its value when p=2​

Answer 1

Answer:I):7p+3

I):17

Step-by-step explanation:

=3p(4p-5)+3

=(12p-5p)+3

=(7p)+3

=7p+3

When p=2

=(7*2)+3

=14+3

=17

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:-$p=2.$

             To find:- Value of above expression $3p(4p-5)+3.$

             Solution:-

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

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

       Now put the value of p in the given equation we get,

        $3p(4p-5)+3\\=>3\times(2)\times(4\times(2)-5)+3\\=>6\times(-40)+3\\=>-237.$

         Hence we will get the value is $-237.$
