Answer:

x^{4} - x³ - 15x² - 61x - 36

Step-by-step explanation:

Given

(x² - 5x - 4)(x² + 4x + 9)

Each term in the second factor is multiplied by each term in the first factor, that is

x²(x² + 4x + 9) - 5x(x² + 4x + 9) - 4(x² + 4x + 9) ← distribute parenthesis

= x^{4} + 4x³ + 9x² - 5x³ - 20x² - 45x - 4x² - 16x - 36 ← collect like terms

= x^{4} - x³ - 15x² - 61x - 36

Suppose we wish to construct the perpendicular bisector of line segment EF. We can correctly begin by placing the compass point
julia-pushkina [17]
- to a point which is more than halfway to the point F. Then draw an arc  around the point. Next place the compass point at  F and,  keeping the same distance between the points of the compass,  draw another arc so as to intersect the first arc at 2 points above and below the line EF. Finally draw a line passing through these 2 points of intersection.  This is the perpendicular bisector of EF.
