Find the product (x+2)(x+3)

Katyanochek1 [597]

Answer:

$x^{2}$ +5x+6.

Step-by-step explanation:

Here you can use the foil method.

1. Multiply x by x to get $x^{2}$ .

2. Multiply x by 3 to get 3x.

3. Multiply 2 by x to get 2x.

4. Multiply 2 by 3 to get 6.

Now, you have to add all those terms to get $x^{2}$ +3x+2x+6 and you can simplify that to $x^{2}$ +5x+6.

Five less than twice what negative number squared is 157?

fenix001 [56]

Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0
