Solving Quadratics by Completing the Square, Quadratic Formula, and Factoring

Which method will work well for ANY quadratic equation?

• Factoring

• Square Root

• Completing the Sqare

• Quadratic Formula

When will a quadratic equation have no solution?

• When it does not equal 0.

• When there is a negative in the square root.

• When there is a bx term.

• When there is no product/sum numbers.

What is this?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.

Which of the following is not the same as "solution"?

• x-intercept

• roots

• zeros

• y-intercept

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form

• Write down: a=1, b=6, c=-13

• Make it equal 0 by subtracting 3 on each side

• Type it all in a calculator.

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Which method is MOST EFFICIENT to solve:
5x²  -3x - 7  = 0

• Square Root Method

• Greatest Common Factor (GCF)

• Complete the Square

• Quadratic Formula

The discriminant is

• ax²  + bx  +  c

• - b/2a

• b² - 4ac

• b² + 4ac

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

When should you decide to Complete the Square?

• When the a value is larger than 1

• When the middle term is odd

• When a = 1 and the middle term is even
