Identify the trinomial that does not belong. Explain. a. 4x2 - 36x + 81

b. 25x2 + 10x + 1

c. 4x2 + 10x + 4

d. 9x2 - 24x + 16

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
