Answer:

y = 2x - 3

Step-by-step explanation:

Take any tow point from the line

(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\$

$= \frac{-3-[-1]}{0-1}\\\\=\frac{-3+1}{-1}\\\\=\frac{-2}{-1}\\\\=2$

m = 2 & (1, -1)

y - y₁ = m(x -x₁)

y - [-1] = 2(x - 1)

y + 1 = 2x - 2

y = 2x - 2 - 1

y = 2x - 3

Which of the following is the complete list of roots for the polynomial function f(x)= (x^2-2x-15)(x^2+8x+17)

alexgriva [62]

Answer:

The complete set of roots is 5, -3, –4 + i, –4 – i

Step-by-step explanation:

The given polynomial is

$f(x)=(x^2-2x-15)(x^2+8x+17)$

We equate to zero to get:

$(x^2-2x-15)(x^2+8x+17)=0$

$(x^2-5x+3x-15)(x^2+8x+17)=0$

$(x(x-5)+3(x-5)(x^2+8x+17)=0$

$(x+3)(x-5)(x^2+8x+17)=0$

This implies that:

x+3=0,or x-5=0 or $(x^2+8x+17)=0$

x=-3,or x=5

For $(x^2+8x+17)=0$ , we use the quadratic formula to get;

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

where a=1,b=8,c=17

$x=\frac{-8\pm\sqrt{8^2-4(1)(17)} }{2(1)}$

$x=\frac{-8\pm\sqrt{-4} }{2}$

$x=-4-i$ or $x=-4+i$

The complete solution is 5, -3, –4 + i, –4 – i
