X2 - 7x + 9 =0 please leave answer in surf form and simplify ​
777dan777 [17]

Answer:

x = \frac{7}{2} ± \frac{\sqrt{13} }{2}

Step-by-step explanation:

Given

x² - 7x + 9 = 0 ( subtract 9 from both sides )

x² - 7x = - 9

Solve using the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2( - \frac{7}{2} )x + \frac{49}{4} = - 9 +

(x - \frac{7}{2} )² = \frac{13}{4} ( take the square root of both sides )

x - \frac{7}{2} = ± \sqrt{\frac{13}{4} } = ± \frac{\sqrt{13} }{2} ( add

x = \frac{7}{2} ± \frac{\sqrt{13} }{2} = \frac{7+/-\sqrt{13} }{2}

Solve for <br> 3x + 12= -12
oee [108]

Answer:

x = -8

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 12 from both sides:

3x + 12 (-12) = -12 (-12)

3x = -12 - 12

3x = -24

Next, divide 3 from both sides:

(3x)/3 = (-24)/3

x = -24/3

x = -8

x = -8 is your answer.
