Solve the equation by Completing the Square x2 – 10x + 13 = 0

user100 [1]

Answer:

$x=5+\sqrt{12}$

$x=5-\sqrt{12}$

Step-by-step explanation:

$x^2-10x+13=0$

$x^2-10x=-13$

$x^2-10x+(\frac{10}{2})^2 =-13+(\frac{10}{2})^2$

$x^2-10x+(5)^2=-13+(5)^2$

$x^2-10x+25=-13+25\\x^2-10x+25=12$

Factor.

$(x-5)^2=12$

Extract the square root.

$x-5=\frac{+}{} \sqrt{12}$

Add 5

$x=5+\sqrt{12}$

$x=5-\sqrt{12}$

Then find the area S of the region. y=2 x^2, y^2=1/2 x

r-ruslan [8.4K]

Recall that the area under a curve and above the x axis can be computed by the definite integral. If we have two curves

y = f(x) and y = g(x)

such that

 f(x) > g(x)

then the area between them bounded by the horizontal lines x = a and x = b is

To remember this formula we write

3(x+6)=2(4x+14) what is the value of x?

GrogVix [38]

Hi there

3(x + 6) = 2(4x + 14)
3x + 18 = 8x + 28
3x - 8x = 28 - 18
-5x = 10
x= 10/-5
x = -2

Here it is :)
