C. Write each quadratic equation in STANDARD FORM, ax2+bx+c=0, then identify the
values of a, b, &c. Show your solution at the back portion.(5 pts. each)
1.) 3x-2x2=7
2.) 5-2x2=6x
3.) (x+7) (x-7)=-3x
4.) 2x(x-3)=15
5.) (2x-1)2=(x+1)2
Answer:
A B C
- -2x^2+3x-7=0
- -2x^2-6x+5=0
- x^2+3x-49=0
- 2x^3-6x-15=0
- 2x-4=0
Solution for 3 and 5:
3. (x^2-49) = -3x
x^2+3x-49=0
5. 4x-2=2x+2
4x-2x-2-2=0
2x-4=0
