Identify a, b, c

Is this equation in standard form?

8x² - 6x = 1

• yes

• no

• it doesn't have a standard form

Is this equation, what is the "c" value?

8x² - 6x = 1

[HINT: must be equal to 0]

• c = 0

• c = -1

• c = 1

What should you do first to get this equation in standard form?

x² + 6x - 13 = 3

• Write down: a=1, b=6, c=3

• Write down: a=1, b=6, c=-13

• Make one side equal 0 by subtracting 3 on each side

• Type it all in a calculator.

Is this equation in standard form?

2x² - 9x - 35 = 0

• yes

• no

• it doesn't have a standard form

Is this quadratic equation in standard form?
 $4x^2-8x=3$  

• yes

• no

Is this equation in standard form? $x^2-16=0$   

• it doesn't have one

• yes

• no

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

[HINT: must be equal to 0]

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Identify b of the quadratic equation:

x ² + 64=0

• 0

• 1

• -1

• 64
