Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

salantis [7]

Answer:

There are no simple factors to this expression. You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:

$y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}$

For 9x+25=88, Deens wrote the situation "I bought some shirts at the store for $9 each and received a $25 discount. My total bil

Sliva [168]

Total bill would be excluding the discount, so Deens has included the discount on the wrong side of the equation.

So: 9X = 88-25
9X=63
63/9=7
therefore Deens bought 7 shirts

D is the correct one

Step-by-step explanation:

The whole angle equals 72 and the partial angle equals 45

You put

72-45= 27

So 3x=27
