Answer:
3/20, -3/10
Step-by-step explanation:
Its a quadratic equation, use the quadratic formula. (-b+-)/2a
20x^2+3x-2=0
(-3+-)/40
(-3+-9)/40
So you get 6/40=3/20 and -12/40=-3/10
To solve this, you need to isolate/get the variable "c" by itself in the equation:
4c + 8c = -55 + 3c You can first combine like terms (4c and 8c)
12c = -55 + 3c Subtract 3c on both sides
9c = -55 Divide 9 on both sides
