What are the solutions to this quadratic equation x2+6x-5=0
marishachu [46]

Answer:

See Below.

Explanation:

Quadratic Form:

a {x}^{2}  + bx + c

Quadratic Formula:

x =  \frac{ - b +   -  \sqrt{ {b}^{2}  - 4ac} }{2a}

Based on the information given from the question, we can deduce:

a = 1

b = 6

c = -5

Now we can substitute all these values into the formula to find x.

x =   \frac{ - 6 +  -  \sqrt{ {6}^{2}  - 4(1)( - 5)} }{2(1)}  \\  =   - 3 +  \sqrt{14}   \: or \:  - 3 -  \sqrt{14}

Least common denominator of 6/7 and 5/14
Darya [45]

Answer:

14

Step-by-step explanation:

You can‘t simplify 5/14 because 5 is a prime number. So, now you have to convert the 6/7 to 12/14 to match it up to 5/14. They now have a common denominator of 14.

Hope this helps! :)

Which of the following is a polynomial with roots 3, 5i, and −5i?
jek_recluse [69]
x_{1}=3 \\  \\ x_{2}=5i \\  \\ x_{2}=-5i \\  \\ f(x)=(x-x_{1})(x-x_{2})(x-x_{3})=(x-3)(x-5i)(x+5i)= \\  \\ =(x-3)(x^{2}+25)=x^{3}+25x-3x^{2}-75=x^{3}-3x^{2}+25x-75

write the equation that describes the line in slope-intercept form. slope = 4, point (3, −2) is on the line y = 4x 14 y = 4x − 2
amid [387]
Equation of a line is given by y - y1 = m(x - x1) where m is the slope and (x1, y1) is any point on the line.

y - (-2) = 4(x - 3)
y + 2 = 4x - 12
y = 4x - 12 - 2
y = 4x - 14
