Question

if p=-7 ,q=12 and x2 + px +q=0 then find the value of x

Answer 1

p=-7 ,q=12 
we know x2 + px +q=0
2x+ -7x  +12=0
-5x+12=0
-5x=0-12
-5x=-12
x=12/5
pls mark as brainliest

Answer 2

Heya aadnan..


Bro..

It’s a nice quetion..as well som times cInfuses as.


Before solving let’s look that it’s a quadratic equation so

There will be two values for the solution

So my brother let’s go with the solution and at last if any doubt arises uh can straight forward ask me then and there so as to get the concept easily


.......................



As values given

P= -7
Q=12


We are putting in our question so
——————————————————-

We will get a quadratic equation like this.






X2-7x+12=0

Now uh might have learnt in your class
The method of factorization.


In which we break our middle term.


So here we’ve with our solution..

————////-/——————————-


X2-4x-3x+12=

So we arrive with our answers



By taking out the common and equating with zero.


X=3 and x=4.






Hope aadnan it was helpful.


Thanks..dude


Njoy.
