Activity 4: Set Me to My Standard! Directions: Write each quadratic equation in standard form,
ax2 + bx + c = 0 then identify the values of a, b, and c. Show your solutions, use another sheet
(intermediate pad).
ax2 + bx + c = 0 a. b. c.
1. x^2-6×-7=0
2. x^2-64=0
3. -2×+8= -9×^2
4. x^2 = 3×+10
5. 4×^2 - 2 =0
6. 2×(x+1)=0
7. (x + 4)^2 =5
8. (x + 5)(x-3)= x (4× + 5)
9. (× + 5)(×-9) =21
10. x(2x-4)=(x-2)(x-2)
