Review Before Solving Quadratics Quiz IM2 Foundations

Simplify:

 $5\pm6$  

• 11

• -1

• 11 or 1

• 11 or -1

What is the difference between solving and factoring?

• There is no difference

• Solving means finding a particular answer for the variable (x equals something) Factoring is the opposite of distribution

• Solving is just getting the answer for any problem. Factoring is putting something into factored form.

Solve by using square roots:

 $x^2=49$  

•  $x=\pm7$  

• x = 7

• x = -7

•  $x=\pm24.5$  

Solve by factoring:

 $\left(x+5\right)\left(x-4\right)=0$  

•  $x^2+x-20=0$  

• x = -5 and x = 4

• x = 5 and x = -4

• x = -5 and x = 4

What does this dude say in this scene?

• Luke, I am your father

• No, I am your Father

• Obi-Wan told me you killed him!

• Bruh, I'm really like your father. For real tho

What factoring method should you use to factor this problem and why?

 $5x^2-14x-3$  

• Diamond because a is equal to 1

• Long diamond because a is not equal to 1

• GCF

• Long Diamond because a is equal to 1

What is the GCF in this problem?

 $6x^4+7x^2+8x$  

• 6x

• x

•  $2x^2$  

• 2x

What's the first step when you solve by factoring?

• Factor the problem

• Get one side of the equation equal to 0

• Set each factor equal to 0
