Find all other zeros of P(x) = x + 2x² - 16, given that -2 + 2i is a zero.
(If there is more than one zero, separate them with commas.)
PLEASE I AM STUCK
Given :
Find all other zeros of P(x) = x + 2x² - 16, given that -2 + 2i is a zero.
To Find :
The other zero.
Solution :
We know, complex solutions only comes in pair, means if one solution of a quadratic equation is complex then other is also complex.
Also, both the roots are conjugate of each other.
( Conjugate of (a + ib) is (a - ib) )
So, conjugate of (-2 + 2i) is (-2 - 2i).
Therefore, other zero of the given equation P(x) = x + 2x² - 16 is ( -2 - 2i ).

What do your models show about removing sets of positive counters? removing sets of negative counters?
Answer:
When you remove a set positive counter the number decrease
When you remove a set of negative counter the number increases
Step-by-step explanation:
When you remove a set positive counter the number decrease it's like subtracting like adding a negative counter (-)
Example: 10 - 5 = 5
When you remove a set of negative counter the number increases it's like adding a positive counter (+)
Example: -10 - (-5) = -5
prove that:
[tex] {sin}^{2} \: \frac{7\pi}{8} + \: {sin}^{2} \: \frac{5\pi}{8} = 1 [/tex]
Recall that
sin²(x) = (1 - cos(2x))/2
so that
sin²(7π/8) = (1 - cos(7π/4))/2
sin²(5π/8) = (1 - cos(5π/4))/2
Then
sin²(7π/8) + sin²(5π/8) = (1 - cos(7π/4) + 1 - cos(5π/4))/2
… = 1 - 1/2 (cos(7π/4) + cos(5π/4))
… = 1 - 1/2 (1/√2 - 1/√2)
… = 1

Multiply (x + - 1)3
(x + 1)3 = (x + 1)(x + 1)2
= (x + 1)(x2 + 2x + 1)
= x + 1x2 +
x +
Answer: (x +-1)3 (x + 1)3 = (x + 1)(x + 1)2
= (x + 1)(x2 + 2x + 1)
= x3 + 3 x2 + 3x + 1
Step-by-step explanation:
Multiplication is a method of finding the product of two or more numbers
when we multiply (x + - 1)3 (x + 1)3 we get (x³-3x²+3x-1)( x³+ 3 x² + 3x + 1)
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
We need to multiply
(x + - 1)³ (x + 1)³
(x - 1)³=(x-1)(x - 1)²
=(x-1)(x² - 2x + 1)
=x³-2x²+x-x²+2x-1
=x³-3x²+3x-1
(x + 1)³ = (x + 1)(x + 1)²
= (x + 1)(x² + 2x + 1)
= x³+ 3 x² + 3x + 1
So (x³-3x²+3x-1)( x³+ 3 x² + 3x + 1)
Hence when we multiply (x + - 1)3 (x + 1)3 we get (x³-3x²+3x-1)( x³+ 3 x² + 3x + 1)

A man drives 500 metres up a road which is inclined at 30° to the horizontal. How
high above his starting point is he?
Step-by-step explanation:
Height = 500sin30° = 500(0.5) = 250.
The height of the man above his starting point is 250m
Trigonometry identityTrigonometry identity expressed the sides of the triangle with the angles.
According to the SOH CAH TOA identity
sin theta = opp/hyp
sin 30 = H/500
Cross multiply
H = 500sin30
H = 500(0.5)
H = 250
Hence the height of the man above his starting point is 250m
