Question

I
20) Factorise : 3x^2+x-14​

Answer 1

Answer:

In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity.

Answer 2

Step-by-step explanation:

3x^2 + x -14

3x^2 + 7x -6x -14

x ( 3x + 7) -2( 3x + 7)

=> ( x - 2) ( 3x+7)
