Sure! So you need to make an addition problem, for example, 200+25; that equals 225, right? Now you need to subtract from 225. For example, 225-10= 215. Hope I helped!
Step-by-step explanation:
y = -2x² + 4x + 1
Complete the square.
y = -2 (x² − 2x) + 1
y = -2 (x² − 2x + 1) + 1 − (-2)(1)
y = -2 (x − 1)² + 3
The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.

1 is D, 2 I'm not sure, 3 is a and b, 4 is a.
Answer:
x1 = 0.16203454
x2= 0.04843273+0.06766624j
x3= 0.04843273-0.06766624j
Step-by-step explanation:
The better way to obtain roots of a polynomial when is not easy to analytically factorize is to use software as Matlab or Python. Use the following code in Python
import numpy as np
pol=np.array([1,-0.2589, 0.02262,-0.001122])
roots=np.roots(pol)
print(roots)
Step-by-step explanation:
70+60+8x+2= 180
132+8x=180
8x=48
x=6°
8x+2= 50°
