Sviatoslav solved the quadratic equation x^2-x-1=0 by completing the square. In the process, he came up with the equivalent equa

zimovet [89]

Answer:

$x=\frac{1+\sqrt5}{2}$ and $x=\frac{1-\sqrt5}{2}$

and b= $\frac{5}{4}$

Step-by-step explanation:

We are given that a quadratic equation

$x^2-x-1=0$

We have to solve the equation by completing square and find the value of b.

$(x)^2-2\times x\times \frac{1}{2}+(\frac{1}{2})^2-(\frac{1}{2})^2-1=0$

$(x-\frac{1}{2})^2-\frac{1}{4}-1=0$

$(x-\frac{1}{2})^2-\frac{1-4}{4}=0$

$(x-\frac{1}{2})-\frac{5}{4}=0$

$(x-\frac{1}{2})^2-(\frac{\sqrt5}{2})^2=0$

$(x-\frac{1}{2})^2=(\frac{\sqrt5}{2})^2$

$x-\frac{1}{2}=\frac{\sqrt5}{2}$ and $x-\frac{1}{2}=-\frac{\sqrt5}{2}$

$x=\frac{\sqrt5}{2}+\frac{1}{2}=\frac{1+\sqrt5}{2}$

And $x=\frac{1}{2}-\frac{\sqrt5}{2}=\frac{1-\sqrt5}{2}$

Therefore, $x=\frac{1+\sqrt5}{2}$ and $x=\frac{1-\sqrt5}{2}$

and b= $\frac{5}{4}$

-9x +y =17 9x + 9y=19<br> solve for y equation 1

OLEGan [10]

Solution1: 9(x) + (y) = 17

Solution 2: 9(x) + 9(y) = 19

Your graphic organizer ➡(y) - 9(x) = 17
9(y) + 9(x) = 19

(y) = 9(x) + 17(⬅Solution 1)

9(x) + 9(9)(x)+17 = 19 ; 90(x) = -134(⬅Solution 2)

(x) = -67÷45
= -1.48

y = 18 ÷ 5
=3.6.

x-intercept ➡ -67/45

y-intercept: 18/5
⬆

y = 3.6; 18/5 (if that's what you're looking for)
