Quiz: Factoring GCF, a=1, and a>1

What is the GCF? 5x²+20x

• 5
• x
• 5x
• 20x

Factor by using GCF:
8n³ + 2n²

• 2n²(4n-1)
• 2n²(4n + 1)
• n²(8n+2)
• 3n(4n+1)

Factor out the GCF

3x³ + 9x

• 3x (x² + 3)

• 3x ( x³ + 9)

• x (3x² + 9)

• 3x (x³ + 3x)

39y⁵ + 12y⁴ - 3y³

• 3y(13y⁴ + 4y³ - y²)
• 3y³(13y² + 4y - 1)
• y³(39y² + 12y - 3)

Factor
49m³q² - 35mq² - 42m³q⁴p²

• 7mq²(7m²q - 5 - 6m²p²q²)
• 7mq²(7m³q - 5mq - 6m²p²q³)
• 7mq²(7m² - 5 - 6m²p²q²)
• 7mq²(7mq - 5 - 6m²pq²)

what is the greatest common factor of the three terms in the expression
-24m³n⁵p + 24mn⁴p² + 4mn⁵

• 4mn
• 24mn⁴
• 4mn⁴
• 4mn⁴p

Factor
-10xy⁹z + 8y³z⁵

• -2y⁴z(20xy⁶ - 4z⁴)

• -2y³z(5xy⁶ - 4z⁴)

• -2y³z(5xy⁶z - 4z⁵)

• -2y³z(5xy⁶z - 8z⁴)

Factor
k²+7x+10

• (k+2)(k+5)
• (k-2)(k-5)
• (k+10)(k+4)
• (k+2)(k-5)

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)
