Question

Will give Brainly to the best answer!!!!! Please help!!!!

Answer 1

Answer:

X= -1

Step-by-step explanation:

how u can see I apply the formula, and I have two answers X1= -1 and X2= -1

U only need to see the information that they give u, it was x^2+2x+1=0

and we know that

a= 1

b=2

c=1

then you replace in the formula and do the exercise:)

Answer 2

Answer:

x=-1

Step-by-step explanation:

here is an example for my class, these really helped

A quadratic equation is any second-degree polynomial equation — that’s when the highest power of x, or whatever other variable is used, is 2. The solution or solutions of a quadratic equation,

Solve the equation,

 

with the quadratic formula:

Bring all terms to one side of the equation, leaviign

Plug the coefficients into the formula.

In this example, a equals 2, b is –5, and c is –12, so

You can also use the quadratic formula for factoring trinomials.

Here’s what you do.

Use the quadratic formula to get solutions for x. (You can also use your calculator to get the solutions.) Make sure the solutions are written as fractions rather than as decimals and that they’re reduced to lowest terms.

Take the two solutions and put them in factors. If a solution is positive, use subtraction. If a solution is negative, use addition.

If either solution is a fraction, take the denominator and bring it in front of the x.

 

And, voilà, the trinomial is factored:

(x – 4)(2x + 3)
