Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ±
( subtract 6 from both sides )
x = - 6 ±
← exact solutions
Answer:

Step-by-step explanation:
The vertex form of a quadratic equation <em>y = ax² + bx + c:</em>
<em>y = a(x - h)² + k</em>
(h, k) - coordinates of a vertex
We have the equation <em>y = x² - 6x + 6</em>.
Convert to the vertex form:

Answer:
the number is 21
Step-by-step explanation:
(9+x)(4)=120
9+x=30
x=21
19.99 + 15= 34.99
40-34.99 = 12.51
