The quadratic formula is:
and
Let's identify our a, b, and c values:
a: -1
b: 1
c: 12
Plug in the values for a, b, and c into the equation. Let's do the first equation:
Simplify everything in the radical:
Simplify the radical:
Combine like terms:
Simplify:
This is one solution, now, let's solve for the other equation:
Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:
Combine like terms:
Simplify:
Your final answers are:
Answer:
4826809 and 6
Step-by-step explanation:
(a)
Given
{ 5² + 12² }³ ← evaluate contents of bracket
= (25 + 144)³
= 169³
= 4826809
(b)
Evaluate contents of parenthesis
= (1 + 8 + 27) = 36, that is
= = 6
