5. Given (x + 1) and (x-3) are factors of P(x) = x4-5x³-7x² + cx + d. Determine the values

Iteru [2.4K]

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.

<h3>How to determine the missing coefficients of a quartic equation</h3>

A value x is a root of a polynomial if and only if p(x) = 0. We must replace the given equation with the given roots and solve the resulting system of <em>linear</em> equations:

(- 1)⁴ - 5 · (- 1)³ - 7 · (- 1)² + (- 1) · c + d = 0

- c + d = 1 (1)

3⁴ - 5 · 3³ - 7 · 3² + 3 · c + d = 0

3 · c + d = 117 (2)

The solution of this system is c = 29 and d = 30.

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.

9x² - 12x + 4 <br><br>pls need ans.

kolezko [41]

Step-by-step explanation:

$\tt{9 {x}^{2} - 12x + 4}$

Here, the second order of polynomial ax² + bx + c is factorized and expressed as the product of two linear factors. First, we have to find the two numbers that adds to 12 and if we multiply those numbers , we get 36 ( The two numbers should be 6 and 6 ).

⟶ $\tt{9 {x}^{2} - (6 + 6)x + 4}$

⟶ $\tt{9 {x}^{2} - 6x - 6x + 4}$ { Distribute x through the parentheses )

⟶ $\tt{ \underbrace{9 {x}^{2} - 6x}} \: - \underbrace{6x + 4}$

⟶ $\tt{3x(3x - 2) - 2(3x - 2)}$

⟶ $\tt{(3x - 2)(3x - 2)}$

⟶ $\tt{ {(3x - 2)}^{2} }$

$\pink{ \boxed{ \boxed{ \tt{ Our \: final \: answer : \boxed{ \underline{ \tt{{(3x - 2)}^{2} }}}}}}}$

Hope I helped ! ♡

A rectangular field measures 227 by 56 yards. How far is it to walk from one corner of the field to the opposite corner? How far

GaryK [48]

Answer:

233.8 Yards

Step-by-step explanation:

Given that,

Length of a rectangular field, l = 227 yards

Breadth of a rectangular field, l = 56 yards

Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,

$x=\sqrt{l^2+b^2} \\\\x=\sqrt{(227)^2+(56)^2} \\\\x=233.8\ \text{Yards}$

So, the distance from one corner of the field to the opposite corner is 233.8 Yards.

Find the surface area of the prism. Picture attached.

vampirchik [111]

Answer:

18.2m^2

Step-by-step explanation:

2 x 1 ÷ 2 = 1 both sides are set to 1

base 3 x 1 = 3

2.2 x 3 = 6.6

add up all sides 6.6 + 6.6 + 3 + 1 + 1
