How do you know if an equation Cannot be factored?

The most reliable way I can think of to find out if a polynomial is factorable or not is to plug it into your calculator, and find your zeroes. If those zeroes are weird long decimals (or don’t exist), then you probably can’t factor it. Then, you’d have to use the quadratic formula.

What if a function Cannot be factored?

Depends what you mean by cannot be factored. If it can’t be factored with integer values, it’s possible it could still be factored with real values. If it can’t be factored with real values, then it has no real roots. It can then be factored with complex numbers to get solutions in the complex number domain.

When can you not factor an expression?

An expression is in factored form only if the entire expression is an indicated product. Factoring is a process that changes a sum or difference of terms to a product of factors. A prime expression cannot be factored. The greatest common factor is the greatest factor common to all terms.

Can not be factored?

A polynomial with integer coefficients that cannot be factored into polynomials of lower degree , also with integer coefficients, is called an irreducible or prime polynomial . is an irreducible polynomial.

How do you find the zeros of a function that Cannot be factored?

Find zeros of a polynomial function

  1. Use the Rational Zero Theorem to list all possible rational zeros of the function.
  2. Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
  3. Repeat step two using the quotient found with synthetic division.

What does it mean when you cant factor a quadratic equation?

READ:   How do you forgive yourself for missing opportunities?

When asked to solve a quadratic equation that you just can’t seem to factor (or that just doesn’t factor), you have to employ other ways of solving the equation, such as by using the quadratic formula. The quadratic formula is the formula used to solve for the variable in a quadratic equation in standard form.

Is it possible to factor X² 4 Why?

x2+4 cannot be factored using real number coefficient.

What method did you used to determine if it is a factor or not?

Any time you divide by a number (being a potential root of the polynomial) and get a zero remainder in the synthetic division, this means that the number is indeed a root, and thus “x minus the number” is a factor.

How do you factor x^2+5x+4?

If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that. Add up to 5. Multiply together to get 4. Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1) (x+4)
