Question

factorise 2x^2 +7x +3​

Answer 1

Answer:

• Here it is.......................
• 2x^2+7x+3
• 2x^2+6x+x+3
• 2x(x+3) +1(x+3)
• x= -1/2, -3

Answer 2

★ Given :

Polynomial : 2x² + 7x + 3

$\rule{200}{1}$

★ To Find :

We have to factoris the polynomial by spliting the middle term.

$\rule{200}{1}$

★ 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

$\rule{200}{1}$

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
