★ Given :
Polynomial : 2x² + 7x + 3
★ To Find :
We have to factorise the polynomial by spliting the middle term.
★ Solution :
Making factors of polynomial.
→ 2x² + 6x + 1x + 3 = 0
→ 2x(x + 3) + 1(x + 3) = 0
→ (2x + 1)(x + 3) = 0
→ 2x + 1 = 0
→ 2x = -1
→ x = -1/2
Or
→ x + 3 = 0
→ x = -3
For factorising we have to follow these given below steps :
Let polynomial be ax² + bx + c = 0
- Firstly we will multiply a and c.
- Then we will make the factors of their product.
- The factors must be equal to b on adding or subtracting.
- Then, we will take common
