Answer:
The quadratic equation form is x² - 9 x + 14 = 0
Step-by-step explanation:
Given in the question as ,
The solution of quadratic equation are x = 2 and x = 7
The constant K is a non-zero number
Now , let the quadratic equation be , ax² + bx + c = 0
And sum of roots =
product of roots =
So, 2 + 7 =
Or, 2 × 7 =
I.e = 9 ,
= 14
Or, b = - 9 a And c = 14 a
Put this value of b and c in standard form of quadratic equation
I.e ax² + bx + c = 0
Or, ax² - 9 ax + 14 a = 0
Or , a ( x² - 9 x + 14 ) = 0
∴ a = 0 And x² - 9 x + 14 = 0
Hence , The quadratic equation form is x² - 9 x + 14 = 0 Answer
d(-3 + x) = kx + 9
- Distribute d inside the parentheses.
-3d + dx = kx + 9
- Subtract kx from both sides.
-3d + dx - kx = 9
- Add 3d to both sides.
dx - kx = 9 + 3d
- Factor x out of dx - kx.
x(d - k) = 9 + 3d
- Divide both sides by d - k.
x =
- If you want to simplify this even more, factor 3 out of the numerator.
