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
