Question

factorize the expression x2 plus 5x plus 6

Answer 1

Answer:

x2 + 5x + 6.

Step-by-step explanation:

Factorize x2 + 5x + 6.

We need to factorise the given equation

Given equation

x2 + 5x + 6

Let us try factorizing this polynomial using splitting the middle term method.

Factoring polynomials by splitting the middle term:

We need to find two numbers ‘a’ and ‘b’ such that a + b =5 and ab = 6.

On solving this we obtain, a = 3 and b = 2

Thus, the above expression can be written as:

x2 + 5x + 6

= x2 + 3x + 2x + 6

= x(x + 3) + 2(x + 3)

= (x + 3)(x + 2)

Thus, x+3 and x+2 are the factors of the polynomial
