Question

The value of 3x(4x - 5) +3 is equal to​

Answer 1

Step-by-step explanation:

:::The value of 3x(4x-5)+3=12x^2-15x+3....

:::It is a value of given expression....

Answer 2

Step-by-step explanation:

Given that : 3x(4x-5)+3

=>12x^2-15x+3

=>12x^2-12x-3x+3

=>12x(x-1)-3(x-1)

=>(x-1)(12x-3)

therefore 3x(4x-5)+3=(x-1)(12x-3)

to get x values (x-1)=0 or(12x-3)=0 therefore values of x are 1 and 3/12=1/4

check:

If x=1,

3×1(4×1-5)+3

=3(4-5)+3

=-3+3

=0

If x=1/4,

3×1/4(4×1/4-5)+3

=3/4(1-5)+3

=(3/4×-4)+3

=3-3

=0

1 and 1/4 satisfies the given polynomial ,so they

are zeroes .
