You need to continue to simply it until it is in the form x^2 +bx+ c. Then try the box and diamond method.

I need help answering 6x+8=26

melomori [17]

First you subtract 8 from 26, which is 18. Then you divide 18 by 6, which is 3. x equals 3.

Find the slope and the equation for the line passing through the points: (-3,0) and (-1,2)

dusya [7]

Answer:

slope: 1
equation: y = x +3

Step-by-step explanation:

The slope of the line between two points can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (2 -0)/(-1 -(-3)) = 2/2

m = 1 . . . . . the slope of the line is 1

The value of the y-intercept can be found by solving the slope-intercept equation for b.

y = mx +b

b = y -mx

b = (0) -(1)(-3) = 3 . . . . . using point (x, y) = (-3, 0)

The equation of the line with slope 1 and y-intercept 3 can be written as ...

y = x +3

Write the quadratic equation that has roots -1-rt2/3 and -1+rt2/3 if its coefficient with x^2 is equal to 1

weeeeeb [17]

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9

<h3>How to determine the quadratic equation?</h3>

From the question, the given parameters are:

Roots = (-1 - √2)/3 and (-1 + √2)/3

The quadratic equation is then calculated as

f(x) = The products of (x - roots)

Substitute the known values in the above equation

So, we have the following equation

$f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})$

This gives

$f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})$

Evaluate the products

$f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})$

Evaluate the like terms

$f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}$

So, we have

f(x) = x²+ 2/3x - 1/9
