a) \(0x^2 + 5x + 9 = -5x^2 + -9x + 63\)

b) \(9x^2 - 12x + 4 = 5x^2 - -5x + 4\)

c) \(63x^2 + -5x + 25 = 5x^2 + -9x + 25\)

d) \(16x^2 + 20x + 6 = 0x^2 + -9x + 6\)

e) \(5x^2 - -5x + 100 = 0x^2 + 63x + 100\)

f) \(25x^2 - 20x + 4 = 63x^2 - 5x + 4\)

g) \(-9x^2 + -5x + 144 = 16x^2 + 63x + 144\)

h) \(63x^2 - 24x + 36 = 4x^2 - -9x + 36\)

i) \(0x^2 - -5x + 225 = 25x^2 + 20x + 225\)

j) \(4x^2 - 16x + 16 = 5x^2 - 0x + 16\) +26
