Factoring VS Solving Quadratics

What do you call a polynomial that cannot be factored?

• FOIL
• Simplified
• Prime
• Proper

What is a method of checking your work when factoring?

• FOIL
• asking the teacher every time
• assume you're correct
• division

Factor
n² + 16n + 63

• (n-7)(n+4)
• (n+7)(n-9)
• (n-3)(n-10)
• (n+7)(n+9)

Factor
k² -2k - 24

• (k+4)(k-6)
• (k+4)(k+6)
• (k+6)(k-1)
• (k-4)(k+6)

Factor
3v² - 4v - 7

• (3v-7)(v+1)
• 3(v-7)(v-1)
• (3v+1)(v-9)
• (3v+1)(v-10)

Factor
3x² + 17x + 10

• (3x-2)(x-5)
• (3x+2)(x+5)
• (3x-5)(x-2)
• (3x+5)(x+2)

Factor completely:  3x² + 18x +15 Hint: Factor GCF first.

• 3(x² + 6x + 5)
• (x + 5)(x + 1)
• 3(x + 5)(x + 1)
• Prime

• a = -8

• a = -2

• a = 2

• a = 8

• a = 0

Solve the equation. v² + 2v -15 = 0

• v = -3 or v = -5

• v = 3 or v = -5

• v = -3 or v = 5

• v = 3 or v = 0

Solve the equation. 2m² + 13m +20 = 0

• m = 1/4 or m = 5

• m = -5/2 or m = 2

• m = -5/2 or m = -1

• m = -5/2 or m = -4
