Answer:
Step-by-step explanation:
I dont quite understand the problem but this is one way to solve it using completing the square:-
2x^2 + 8x - 12 = 0
2(x^2 + 4x) - 12 = 0
2((x + 2)^2 - 4) = 12
2(x + 2)^2 - 8 + 8 = 12 + 8
2(x + 2)^2 = 20
The value of 4 in 34,258 is 10 times the value of the 4 in 47,163.
