Question

If a=2,b=3 and c=4 find the value of. b²-2bc+c²

Answer 1

put the values of a, b and c in the expression.

(3)²-2(3)(4)+(4)² = 1

Answer 2

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

           Given data:- $a=2,b=3,c=4.$

           To find:- Value of above expression $b^{2} -2bc+c^{2} .$

           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 a and b in the given equation we get,

         $b^{2} -2bc+c^{2} \\=3^{2} -2(3)(4)+4^{2}\\=9-24+16\\=9-8\\=>1$

      Hence we will get the value is $1.$
