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

  1. -2x^2+3x-7=0
  2. -2x^2-6x+5=0
  3. x^2+3x-49=0
  4. 2x^3-6x-15=0
  5. 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
