Name: Geometry
Date: Quiz 4
In 1-8, factor completely.
1. 6x + 27 2. 14x3y5 – 21x5y2 3. a2 - 10a + 25
4. m2 – 49 5. 3d2 – d – 10 6. t2 + 6t – 55
7. 6xy – 2x2 8. 8 – x 9. 8x2 – 32
x – 3y x2 + x – 72
In 10-15, solve for x.
REMINDER: Get everything into the form ax2 + bx + c = 0
10. x2 – 71 = 10 11. 5x2 = 3x – 2 12. 5d2 = 125
13. 3x2 + 8 = 35 14. x2 + 14x = -40 15. 3x2 + 8x +5 = 0
BONUS: Write an equation in the form ax2 + bx + c = 0 if the solution of the equation is 4 and –2.
