<u>x² + 3x + 3 = 0</u>
I can tell by looking that there's no easy way to factor the left side,
so we'll have to use the Quadratic formula.
Before doing that, let's just take a look at the discriminant:
( B² - 4AC ) = (9) - (4 x 3 x 1) = (9 - 12) = -3 .
The discriminant is negative, so we know that the roots will be complex conjugates.
Again: <u>x² + 3x + 3 = 0</u>
x = (1/2) [ -3 plus or minus the square root of (-3) ]
<u>x = -3/2 + (1/2) j√3</u>
and
<u>x = - 3/2 - (1/2) j√3</u>
Answer:
x=20 y=34
Step-by-step explanation:
x+14=2x-6
x=20
(20)+14=y
y=34
Answer:
The probability that she chooses a nuumber less than 4 is 30%
Step-by-step explanation:
Answer:
Final answer is 13.
Step-by-step explanation:
Given expression is
-k+h+kh
We also have been given values of h and k as:
k=-5 h=-2
to simplify the given expression, we just need to plug the given values of k=-5 and h=-2 into -k+h+kh
-k+h+kh
Hence final answer is 13.
