From the quadratic equation 3x² + X - 5 = 0, find alpha square plus beta square

timama [110]

Answer:

α² +β² = 3 4/9

Step-by-step explanation:

Assuming α and β are solutions to the equation, it can be factored as ...

(x -α)(x -β) = 0

Expanding this, we get ...

x² -(α +β)x +αβ = 0

Dividing the original equation by 3, we find ...

x² +(1/3)x -5/3 ≡ x² -(α+β)x +αβ ⇒ (α+β) = -1/3, αβ = -5/3

We know that the square (α+β)² can be expanded to ...

(α +β)² = α² +β² +2αβ

α² +β² = (α +β)² -2αβ . . . . . . subtract 2αβ

Substituting the values for (α+β) and αβ, we find the desired expression is ...

α² +β² = (-1/3)² -2(-5/3) = 1/9 +10/3 = 31/9

α² +β² = 3 4/9

What is the rate of change between (29,9) and (33,10)?

Tema [17]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

The rate of change is a measure of the slope

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)

m = $\frac{10-9}{33-29}$ = $\frac{1}{4}$ ← rate of change

Find the slope of the line passing through the points (-2,5) and (3/2, 2).

sveticcg [70]

Answer:

The answer is

Step-by-step explanation:

The slope of the line passing through two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (-2,5) and (3/2, 2)

The slope is

<h3> $m = \frac{2 - 5}{ \frac{3}{2} + 2} \\ = - \frac{3}{ \frac{7}{2} } \\ = - 3 \div \frac{7}{2} \\ = - 3 \times \frac{2}{7}$ </h3>

We have the final answer as

Hope this helps you
