Which two values of x are roots of the polynomial below? 3x2-3x+1

QveST [7]

Answer:

The roots are

$x=\frac{1}{6} [3+ i\sqrt{3}]$

$x=\frac{1}{6} [3- i\sqrt{3}]$

Step-by-step explanation:

we have

$3x^2-3x+1$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

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

in this problem we have

$3x^2-3x+1=0$

$a=3\\b=-3\\c=1$

substitute in the formula

$x=\frac{-(-3)\pm\sqrt{-3^{2}-4(3)(1)}} {2(3)}$

$x=\frac{3\pm\sqrt{-3}} {6}$

Remember that

$i=\sqrt{-1}$

$x=\frac{1}{6} [3\pm i\sqrt{3}]$

The roots are

$x=\frac{1}{6} [3+ i\sqrt{3}]$

$x=\frac{1}{6} [3- i\sqrt{3}]$

Find X when y=5 in the literal equation 4x+7y=51

JulijaS [17]

4x+7y=51

Plug in y=5::
4x+7(5)=51

Simplify:
4x+35=51


4x+35-35=51-35

4x=16 (÷4)

x=4

Done :)


 I hope that helps!

Calculate the equation of the line if two points are (1,6) and (5,0). Explain

topjm [15]

Answer:

y = -3/2x+15/2

Step-by-step explanation:

First calculate the slope

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

= (0-6)/(5-1)

= -6/4

= -3/2

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -3/2 x+b

Substitute a point into the equation

0 = -3/2(5)+b

0 = -15/2+b

15/2 = b

The equation is

y = -3/2x+15/2
