Question

1) x^2 + 2x+1=0
find value of a,b,c​

Answer 1

Answer:

a=1,b=2,c=1

Step-by-step explanation:

equate eqn to ax^2+bx+c

Answer 2

Here is your answer

Given equation

= x²+2x+1

By using middle term splitting method

we get

= x²+x+x+1

= x(x+1) +1(x+1)

= (x+1)(x+1)

or = (x+1)²

where x+1= 0

and x= -1

Its the value of x

Now for finding the value of a,b and c

we know

that

Quadratic equation form

= ax²+bx+c

Thus equating this formula with the given equation

we get,

ax²+bx+c= x² + 2x+1

Thus a= 1

b= 2

and c = 1

Here we take out the coefficient of x² ,x

Hope this helps you
