Find the zeros of the following expression x^2+5x+6 show all work
GaryK [48]
Let y = 0 to find the zeros.
x^{2} + 5x + 6 = 0

We can now split the middle term into factors of 6 that add up to 5.
x^{2} + 3x + 2x + 6 = 0

Group the first two terms, and group the last two terms, and factorise.
(x^{2} + 3x) + (2x + 6) = 0
x(x + 3) + 2(x + 3) = 0

Group like terms.
(x + 3)(x + 2) = 0

Now, we know that in order for a zero to occur, either x + 3 = 0 or x + 2 = 0.
Hence, x = -3 and -2 are the zeros in this quadratic.

A cone with volume 5000 m^3 is dilated by a scale factor of 1/5
user100 [1]

ANSWER

The volume of the dilated cone is

40 {m}^{3}

EXPLANATION

The volume of the given cone is

5000 {m}^{3}

When this cone is dilated with a scale factor of 1/5, the volume of the dilated cone becomes,

({ \frac{1}{5} })^{3}  \times 5000 {m}^{3}

We simplify to obtain:

{ \frac{1}{125} }\times 5000 {m}^{3}

This gives us:

40 {m}^{3}
