Mark as branlist please

Step-by-step explanation:

2x^2 −5x +2

Step 1: Multiply degree 2’s coefficient by the term with degree 0 (the constant term). Omit this coefficient from the expression - we will come back to this coefficient later so don't worry!

x^2 −5x +4

Step 2: (Factor this new, transformed expression)

(x−4)(x−1)

Step 3: Now, divide each constant term within each binomial by the original leading coefficient. In this case, it was 2.

(x − 4/2)(x − 1/2)

Step 4: In the first binomial, we are left with a constant term that is an integer- this is fine. However, for the second binomial, we must move the 2 to the front of the degree 1 term since the constant term is a fraction after division by the coefficient of 2.

(x−2)(2x−1)

Note: This trick can be very handy when factoring more complicated polynomials of degree 2. However, it may not be necessary for simpler expressions
