<span>4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
</span>Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9

x = - b </span>± √Δ / 2.a



A. Two real solutions (x' = -1 and x'' = -1/4)
Answer:
angle 2 =90 because it is a right angle
Answer:
<em>56</em>
Step-by-step explanation:
80/100 x 30 = 24 because you just multiply percents
