Question

3x^2-5x-12 answere after factorizing​

Answer 1

Answer:

3x^2-5x-12

=3x^2-(9-4)x-12

=3x^2-9x+4x-12

=3x(x-3)+4(x-3)

=(3x+4)(x-3)

Answer 2

Answer:

3x²-5x-12

3x²-9x+4x-12

3x(x-3) +4(x-3)

(x-3) (3x+4)

zeros of the equation

x-3=0

x=3

3x+4=0

x= -4/3

Hence, the 3x²-5x-12 are factors of 3 or -4/3
