If Lylah completes the square for f(x)=x^2-12x+7 in order to find the minimum, she must write f(x) in the general form f(x)=(x-a
n200080 [17]
X^2-12x+7=0  move constant to other side

x^2-12x=-7  add the square of half the linear coefficient to both sides...(12/2)^2=36

x^2-12x+36=29  now the left side is a perfect square...

(x-6)^2=29 so if

f(x)=(x-a)^2+b then

f(x)=(x-6)^2-29

So a=6

Solve and sketch its graph<br> 1. 3x^2 - 4x = 0
Neko [114]

Step-by-step explanation:

By solving, I am assuming that you want to find the zeros.

So to find what x equals, first, you factor out an x.

3x² - 4x = 0

x(3x - 4) = 0

Here, you can separate the equation into two different equations to solve for x.

  • <em>3x - 4 = 0</em>           and              <em>x = 0</em>
  • 3x = 4
  • x = \frac{4}{3}                   and               x = 0

Those are your zeros.

And for its graph, you can always look to an online graphing calculator. I used Desmos.
