Write one in factor form with solutions 3,-1,-3i?

denpristay [2]

Answer:

Factored form: $(x-3)(x+1)(x^2+9)$

Expanded form: $x^4-2x^3+6x^2-18x-27$

Step-by-step explanation:

$(x-3)(x+1)(x^2+9)$

$(x^2-2x-3)(x^2+9)$

$x^4+9x^2-2x^3-18x-3x^2-27$

$x^4-2x^3+6x^2-18x-27$

$x-3=0$ has a solution of $x=3$

$x+1=0$ has a solution of $x=-1$

$x^2+9=0$ has a solution of $x=\pm 3i$

Find the measure of <_B. (Show your work if possible).

vladimir2022 [97]

Answer:

We know that exterior angle of a triangle is equal to the sum of two opposite interior angles

Step-by-step explanation:

Here

<A = 4y

<B = 3y + 14°

<BCD = 119°

Now

<BCD = <A + <B ( Exterior angle of a triangle is equal to the sum of two opposite interior angle)

119° = 4y + 3y + 14°

119°- 14° = 7y

105° = 7y

Therefore y = 15°

Now < B = 3y + 14°= 3*15° + 14°=59°
