Find the solution for the quadratic equation by completing the square.<br> x^2+18x=63​
vekshin1

Good evening ,

Answer:

<h2>x = 3   or   x = -21</h2>

Step-by-step explanation:

x²+18x=63 ⇌ x²+18x+81 = 63 + 81

⇌ (x+9)² = 144  ⇌ (x+9)² = 12² ⇌ (x+9-12)(x+9+12) = 0

⇌ (x-3)(x+21) = 0

⇌ x=3 or x=-21.

Given that these simultaneous equations
Tatiana [17]

The value of k is(3\sqrt{ 10})/2

<h3>How to solve the simultaneous equation?</h3>

Given:

x-y=k.............(eq i)

2x²+y²-15..............(eq ii)

We would make y the subject formula in eq ii

2x²+y²-15= 0

2x² + y²= 15

y²= 15-2x²

y= \sqrt{15-2x^2}...........(eq iii)

Substitute the value of y into eq i

x-(\sqrt{15-2x^2}= k

x- (\sqrt{15} - 2x= k

k= (3\sqrt{ 10})/2
