Answer 1

Answer:1/2 and -7/2

Step-by-step explanation:

Answer 2

Answer:

c = −4x2−12x+7  /0

Step-by-stepexplanation:

Step 1: Add -c to both sides.

x^2 + 3x + c = 7/4 + c

              -c            -c

x2  + 3x = 7/4

Step 2: Add -x^2 to both sides.

x2 + 3x=  7/4

−x2        −x2

3x = 7/4 -2x

Step 3: Add -3x to both sides.

3x+ = 7/4−x2

-3x         −3x

0 = -x2 -3x +7/4

Step 4: Divide both sides by 0.

0  = -x2 -3x +7/4

/0       /0

c = −4x2−12x+7

         /0

Answer:

c = −4x2−12x+7

         /0
