Answer 2

Question :

$\huge\bold{ {x}^{2} + 7x + 12}$

It is in the form of a quadratic equation e.g.=>$\bold{\red{a {x}^{2} + bx + c}}$

=>A quadratic equation have maximum degree or power 2.

=>There will always two roots of a quadratic equation.

It can be factorise as it is a quadratic equation.

So,let's factorise it to find roots.

procedure for factorise

How to factorise..??

step1: Multiply the constant term with coefficient of x square.suppose we obtain 'z' after multiplying

step 2:Think of a number whose sum equal to the coefficient of middle term and product makes the 'z'

step 3: now split the middle term by factors of that number which you think.

step 4:At last take common and compare with equal to 0 we obtain the roots .

$\bold{\underbrace{ {x}^{2} + 7x + 12}_{12} }= 0$

=>12=4×3

and sum =4+3=7 makes the coefficient of middle term

$= > {x}^{2} + 4x + 3x + 12$

$= > x(x + 4) + 3(x + 4) = 0$

$= > (x + 3)(x + 4) = 0$

Now compare roots equal to 0.

$x + 3 = 0$

$\bold{\red{x = - 3}}$

$x + 4 = 0$

$\bold{\red{x = - 4}}$

Hence ,the roots of given Quadratic equation are

$\bold{\red{x = - 3}}$ ,$\bold{\red{x = - 4}}$
