          2x² + 6x - 4 = 0
2(x²) + 2(3x) - 2(2) = 0
        <u>2(x² + 3x - 2)</u> = <u>0</u>
                 2              2
           x² + 3x - 2 = 0
                          x = <u>-(3) +/- √((3)² - 4(1)(-2))</u>
                                                2(1)
                          x = <u>-3 +/- √(9 + 8)</u>
                                           2
                          x = <u>-3 +/- √(17)
</u>                                         2<u>
</u>                          x = -1.5 <u>+</u> 0.5√(17)
                          x = -1.5 + 0.5√(17)    U    x = -1.5 - 0.5√(17)

Inside a bag of candy there are 16 lollipops, 12 pieces of chocolate, and 7 pieces of licorice. If you reach in the bag and grab
denpristay [2]
The probability of getting a piece of chocolate or a lollipop would be \frac{28}{35}. You can find this by first adding all of the values of the amount of chocolate, lollipops, and licorice. Then, add the value of the amount of chocolate and lollipops.

Factor this problem ?<br> 125 +27y^3
koban [17]

Answer:

(5 + 3y)(25 - 15y + 9y²)

Step-by-step explanation:

This is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²), thus

125 + 27y³

= 5³ + (3y)³ with a = 5 and b = 3y

= (5 + 3y)(5² - 5(3y) + (3y)² )

= (5 + 3y)(25 - 15y + 9y²)
