<u>Algebra II</u>

Imaginary Root <em>i</em> = √-1

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

2x² + x + 67 = 0

<em>a</em> = 2

<em>b</em> = 1

<em>c</em> = 67

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute in variables [Quadratic Formula]: $\displaystyle x=\frac{-1 \pm \sqrt{1^2-4(2)(67)}}{2(1)}$
Multiply: $\displaystyle x=\frac{-1 \pm \sqrt{1^2-4(2)(67)}}{2}$
[√Radical] Evaluate exponents: $\displaystyle x=\frac{-1 \pm \sqrt{1-4(2)(67)}}{2}$
[√Radical] Multiply: $\displaystyle x=\frac{-1 \pm \sqrt{1-536}}{2}$
[√Radical] Subtract: $\displaystyle x=\frac{-1 \pm \sqrt{-535}}{2}$
[√Radical] Simplify: $\displaystyle x=\frac{-1 \pm i\sqrt{535}}{2}$

F(x)= -3x^3-x^2+x-3 identify the end behavior of each polynomial function

sashaice [31]

end behavior is affect by the exponent and whether its negative or positive

y = y^3 starts negative from -∞ to 0 the from 0 to +∞ goes positive

since this equation is negative its switched

-∞ to 0 its positive x>0

0 to +∞ is negative x<0

Find the roots: x^2−12x+32=0. <br><br> Enter your answers in the boxes (numbers only).

AnnZ [28]

The answers are 4 and 8.

Because:

x^2 - 12x + 32 =

(x - 4)(x - 8)

x - 4 = 0

+4 +4

x = 4

x - 8 = 0

+8 +8

x = 8
