The "standard form" of a 2nd order poly is y = ax^2 + bx + c. Therefore, your 2 + 3x + x^2 in "standard form" is y = x^2 + 3x + 2.
Destribute then combined like terms?
Answer:
40°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for third angle
third angle = 180° - (90 + 50)° = 180° - 140° = 40°
