Solve the following equation for x: z=x^2+wx

Mathematics
1 answer:
Alja [10]3 years ago
4 0
Minus z both sides
0=x^2+wx+z
we can use quadratic formula or manually complete the square
let's use quadratic

for
0=ax^2+bx+c
x= \frac{-b+/- \sqrt{b^2-4ac} }{2a}
given
0=1x^2+wx-z
a=1
b=w
c=-z

x= \frac{-w+/- \sqrt{w^2-4(1)(-z)} }{2(1)}
x= \frac{-w+/- \sqrt{w^2+4z} }{2}

x= \frac{-w+ \sqrt{w^2+4z} }{2} or x= \frac{-w- \sqrt{w^2+4z} }{2}

Answer:

  • 5+\sqrt{5}

Step-by-step explanation:

Both are essentially same questions, considering 30 = 25 + 5.

<u>Solving c)</u>

  • \sqrt{25+10\sqrt{5} +5} =
  • \sqrt{5^2+2*5*\sqrt{5} +(\sqrt{5} )^2} =
  • \sqrt{(5+\sqrt{5} )^2} =

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks:
Neko [114]
Quadratic f(x) = (x -h)² +k has vertex (h, k) and axis of symmetry x=h. When k is negative, the number of real solutions is 2, because both branches of the function cross the x-axis.

In your equation, h = -3 and k = -8.

Axis of symmetry: x = -3
Vertex: (-3, -8)
Number of real solutions: 2
