Solve 2x2 – 6x + 10 = 0 by completing the square.

Ugo [173]

Answer:

Step-by-step explanation:

2x^2-6x+10=0

2(x^2-3x)+10=0

2(x-(3/2))^2-9/4)+10=0

2(x-(3/2))^2+10-9/2=0

2(x-(3/2))^2+(20-9)/2=0

2(x-(3/2))^2+11/2=0

2(x-(3/2))^2=-11/2

square is always positive so there is no solution

Jaime has 38 marbles if Jorge had 14 more marbles he would have twice as many as Jaime how many marbles does Jorge have now?

Ganezh [65]

Answer: Jorge has 62 marbles.

Step-by-step explanation: Given that Jaime has 38 marbles if Jorge had 14 more marbles he would have twice as many as Jaime.

We are to find the number of marbles that Jorge has.

Let x and y represents the number of marbles that Jalme and Jorge has respectively.

Then, according to the given information, we have

$x=38$

and

$y+14=2x\\\\\Rightarrow y+14=2\times38\\\\\Rightarrow y+14=76\\\\\Rightarrow y=76-14\\\\\Rightarrow y=62.$

Thus, Jorge has 62 marbles.
