Question

if x =1/2 then find out 3x(4x-5)+3​

Answer 1

here is your answer

3x(4x−5)+3=12x

3x(4x−5)+3=12x 2

3x(4x−5)+3=12x 2 −15x+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3 =108−45+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3 =108−45+3 =66
