Answer:
c = 5
Step-by-step explanation:
A quadratic equation in standard form is
ax² + bx + c = 0 : a ≠ 0
Given
- 6 = x² + 4x - 1 ( add 6 to both sides )
0 = x² + 4x + 5 ← in standard form
with c = 5
A^2 + b^2 = c^2 fill in the know numbers a=4 b=10
$^2 +10^2 = 116
now find the square root of that its
c is approx 10.8
Distributing property because you distribute the 4 to both the x and the -6
