A. Determine if the given equation is linear, quadratic, or neither.
1. \( 4 x - 5 = 6 \)
2. \( 5 x + 7 = 3 ( x - 1 ) \)
3. \( m ^ { 2 } - 5 m - 6 = 0\)
4. \( y ^ { 3 } + 6 y ^ { 2 } - 7 y = 8 \)
5. \( \frac { 1 } { x - 8 } = x + 5\)
B. Write the following quadratic equations in standard form. Give the value of a, b, and \( c \) .
1. \( x ^ { 2 } = 2 x - 1 \)
2. \( 10 m = 7 m ^ { 2 } \)
3. \( 3 + 5 d = 4 d ^ { 2 }\)
\(4 \cdot 14 = 3 x - x ^ { 2 } \)
\( 5 \cdot m ^ { 2 } - 6 m + 5 = 4 m ^ { 2 } - 8\)
Determine the solutions of each quadratic equation using the preseribed method.
A. Extracting Square Roots
1) \( 4 x ^ { 2 } - 81 = 0 \)
2) \( 2 x ^ { 2 } - 32 = 66\)
B. Factoring
3) \( a ^ { 2 } - a - 2 = 0 \)
4) \( x ^ { 2 } + x = 20 \)
5) \( x ^ { 2 } - 22 x = - 120\)
