What are the quadratic equations for x=-14​

Mathematics
1 answer:
raketka [301]3 years ago
4 0

Answer:

x^{2} +14x=0

Step-by-step explanation:

Given:

Given root is

x=-14,\ 0

Now we need to find the quadratic equation for given roots.

Solution:

The given roots are -14 and 0.

So, the sum of the roots.

\alpha +\beta = -14 + 0

\alpha +\beta = -14

Product of the given roots

\alpha\times \beta = -14\times 0

\alpha\times \beta = 0

Therefore, the required quadratic equation is.

x^{2} -(\alpha +\beta )x+\alpha\times \beta=0 -------------------(1)

Now we substitute (\alpha +\beta ) and (\alpha\times \beta) in equation 1.

x^{2} -(-14)x+0=0

x^{2} +14x=0

Therefore, the quadratic equation for the given root is. x^{2} +14x=0

For what value of k will these pairs of simultaneous equations have no solution?
yKpoI14uk [10]
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=\frac{k+3}{k-12}
Also y=\frac{5k}{k-12}
We can not divide with zero.
k-12=0
k=12
For k= 12 equations have no solutions.

Find measure dbc <br> 19<br> 22<br> 23<br> 161 <br> HELP !!!
uysha [10]
∠DBC = 19° since the two angles have to add up to 180, if x = 23, then 23 -4 = 19 for the right, and 7 x 23 = 161, and 161 + 19 = 180.
