Sergio039 [100]

Answer:

$x = - 4$

Step-by-step explanation:

$4x - 2 = - 3 \times 2 + 3x$

Calculate the product:

$4x - 2 = - 6 + 3x$

Rearrange the terms:

$4x - 3x = - 6 + 2$

Combine like terms:

$x = - 6 + 2$

Calculate:

$x = - 4$

Find all real and complex zeros of p(x)=x^3-x^2-4x-6

yuradex [85]

Answer:

x = 3 , -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$

Step-by-step explanation:

⇒ $p(x)=x^{3} -x^{2} -4x-6$

⇒ $p(x)=(x-3)(x^{2} +2x+2)$

now, for zeros of $(x^{2} +2x+2)$ ,

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

⇒ x = $\frac{-2}{2}$ ± $\frac{\sqrt{2^{2}-4(2) } }{2}$

⇒ x = -1 ± $\sqrt{-1}$

hence, all the roots are,

x = 3, -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$

What is the area of a parallelogram whose vertices are A(-12, 2), B6, 2). C(-2,-3), and D(-20, – 3)

guapka [62]

Answer:

-35

Step-by-step explanation:

This value of "a" is exactly the y-coordinate of the vertex of the parabola

y = x%5E2+%2B+4x++-+31.

To find it, complete the square:

x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.

So, this value of "a" is a = -35.
