Multiply polynomial $4 - 5 m$ by $4 - 5 m$ .

Answer

$(4 - 5 m) \cdot (4 - 5 m) = 25 m^{2} - 40 m + 16$

Explanation

Step 1: First we have to write polynomials in descending order.

P (x) Q (x) = - 5 m + 4 = - 5 m + 4

In this example we are multiplying two binomials so FOIL method can be used.

(- 5 m + 4) \cdot (- 5 m + 4) = FIRST (- 5 m) \cdot (- 5 m) + OUTER (- 5 m) \cdot 4 + INNER 4 \cdot (- 5 m) + LAST 4 \cdot 4 = = 25 m^{2} + (- 20 m) + (- 20 m) + 16 = = 25 m^{2} + (- 20 m) + (- 20 m) + 16 = = 25 m^{2} - 40 m + 16;
