2x - x + 3x + 5 = 25 Solve for X

postnew [5]

Answer:

$\bf x=5$

Step-by-step explanation:

$\bf 2x - x + 3x + 5 = 25$

Combine like terms.

$\bf 4x+5=25$

Subtract 5 from both sides.

$\bf 4x+5-5=25-5$

$\bf 4x=20$

Divide both sides by 4.

$\bf \cfrac{4x}{4}=\cfrac{20}{4}$

$\bf x=5$

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square

ladessa [460]

Since we will be completing the square we need to isolate the x

y-5 = 2x^2 -4x

now we the coefficient of the x^2 to equal 1 so we take 2 as common factor

y-5 = 2(x^2 -2x)

now we'll make it perfect square by adding 2 to both sides

y-5+2=2(x^2-2x+1)

now simplify and convert the right side to squared expression

y-3 = 2(x-1)^2

now isolate the y

y = 2(x-1)^2 +3 that's it
