Answer 1

$\huge {\mathfrak {Question :}}$

Factorise : $3 x^2 + 11x + 10$

$\huge {\mathfrak {Solution :}}$

Step 1 :

• Split middle term in two part.

Step 2 :

• Take two numbers whose sum is 11 and multiplication is 30.

Step 3 :

• The required number are 6 and 5.

Step 4 :

• Factorise it in common form.

Step 5 :

• Write first common binomial with small bracket and then remaining in binomial with small bracket.

Step 6 :

• Required factorisation obtained.

$\implies 3x^2+11x+10\\\implies 3x^2+(6+5)x+10\\ \implies 3x^2+6x+5x+10\\ \implies 3x(x+2)+5(x+2) \\ \implies (x+2) (3x+5)$

Answer 2

Answer:

Hello mate✌✌✌

$3 {x}^{2} + 11x + 10 \\ 3 {x}^{2} + 6x + 5x + 10 \\ 3x(x + 2) + 5(x + 2) \\ (3x + 5)(x + 2)$

Hope it helps✌✌✌
