Jimmy is trying to factor the quadratic equation $ax^2 + bx + c = 0.$ He assumes that it will factor in the form \[ax^2 + bx + c

= (Ax + B)(Cx + D),\]where $A,$ $B,$ $C,$ and $D$ are integers. If $a = 4,$ and Jimmy wants to find the value of $A,$ what are the possible values he should check, in order to find $A$?

Answer:

possible value of A are 1, 2, 4

Step-by-step explanation:

Jimmy is trying to factor the quadratic equation ax^2 + bx + c = 0.

He assumes that it will factor in the form ax^2 + bx + c = (Ax + B)(C x + D)

Given a=4

We need to find the value of A

When we do factoring we use the factors of the numbers

(Ax+B)(Cx+D) is ACx^2 + ADx + BCx + BD

ax^2 + bx + c =ACx^2 + ADx + BCx + BD

When a=4  then AC is also 4

A* C = 4

1 * 4= 4

2 * 2= 4

4 * 1 = 4

So possible value of A are 1, 2, 4

If

ax^2+bx+c=(Ax+B)(Cx+D)

then

ax^2+bx+c=ACx^2+(AD+BC)x+BD

\implies a=AC

If a is known and Jimmy wants to find A, then he has to know the value of C.

Answer:

9x² - 9y + 9

Step-by-step explanation:

Step 1: Write out expression

3 - 2y - 1 + 5x² - 7y + 7 + 4x²

Step 2: Combine like terms (x²)

9x² + 3 - 2y - 1 - 7y + 7

Step 3: Combine like terms (y)

9x² - 9y + 3 - 1 + 7

Step 4: Combine like terms (constants)

9x² - 9y + 9

A card is chosen at random from a deck of 52 cards. What is the probability that a king or queen is chosen?
Slav-nsk [51]

The answer is B) 2/13.

An easy way to figure this out is to find what the unsimplified probability would be:

Since there are 8 kings and queens in total, the number is:

8/52

But, since these are both even numbers, they can be simplified.

1/4 x 8 = 2

1/4 x 52 = 13

2/13

Since 13 is a prime number, the answer cannot be simplified anymore.
