Question - Determine Values for Quadratic Expressions

For each quadratic expression, we identify coefficients a, b, and c in the standard form \( ax^2 + bx + c \):

(a) \( 2x^2 - 5x + 1 \): a = 2, b = -5, c = 1

(b) \( x^2 - 2x \): a = 1, b = -2, c = 0

(c) \( 2x^2 + 1 \): a = 2, b = 0, c = 1

(d) \( -\frac{1}{2}p^2 + 4p \): a = -\frac{1}{2}, b = 4, c = 0

(e) \( -1 - x - 2x^2 \): a = -2, b = -1, c = -1

(f) \( 4x^2 \): a = 4, b = 0, c = 0

(g) \( h^2 + \frac{3}{2}h - 4 \): a = 1, b = \frac{3}{2}, c = -4

(h) \( \frac{1}{3}k^2 - 2 \): a = \frac{1}{3}, b = 0, c = -2

(i) \( 2r(r - 3) \): a = 2, b = -6, c = 0
