Question

Factorise the following by spletting the middle term.
1. 7x²+10x+3
2. 3x²-9X+6
3. x²+7x+12
4. 9x²+15x+4
5. 6x²-12x+6
6. 4x²-14x+6​

Answer 1

Answer:

4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴ is a polynomial in one variable.
