Factor polynomials.

Polynomials can have no variable at all. Example: 21 is a polynomial. It has just one term, which is a constant. Or one variable. Example: x4 − 2x2 + x has three terms, but only one variable (x) Or two or more variables. Example: xy4 − 5x2z has two terms, and three variables (x, y and z)Find the product a c. Look for two numbers that multiply to a c and add up to b. Rewrite the b x term into two terms using the numbers we found in step 2. Factor the expression by grouping. Example: Factor 3 x 2 + 8 x + 4. a c = 12. 2 ∙ 6 = 12 and 2 + 6 = 8. Rewrite 8 x as 2 x + 6 x: 3 x 2 + 2 x + 6 x + 4. To completely factor a linear polynomial, just factor out its leading coe-cient: ax+b = a ⇣ x+ b a ⌘ For example, to completely factor 2x+6,writeitastheproduct2(x+3). Factoring quadratics What a completely factored quadratic polynomial looks like will depend on how many roots it has. 0Roots.If the quadratic polynomial ax2 + bx + c has 0 ...When solving "(polynomial) equals zero", we don't care if, at some stage, the equation was actually "2 ×(polynomial) equals zero". But, for factoring, we care about that initial 2. Also, when we're doing factoring exercises, we may need to use the difference- or sum-of-cubes formulas for some exercises. This is less common when solving.

How to factor expressions. 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)To factor a polynomial completely: Identify and factor out the greatest common monomial factor. Break down every term into prime factors. Look for factors that appear in every single term to determine the GCF. Factor the GCF out from every term in front of parentheses and group the remnants inside the parentheses. Multiply each term to simplify.A factor of a polynomial P(x) of degree n is a polynomial Q(x) of degree less than n which can be multiplied by another polynomial R(x) of degree less than n to yield P(x), i.e., a polynomial Q(x) such that P(x)=Q(x)R(x).

Subtract 1 from both sides, you get 2x equals negative 1. Divide both sides by 2, you get x is equal to negative 1/2. So when x equals negative 1/2-- or one way to think about it, p of negative 1/2 is 0. So p of negative 1/2 is 0. So this right over here is a point on the graph, and it is one of the real zeroes.
