How to Evaluate Algebra Expressions?
We are given that;
x = -2
y = -3
z = 5
A) The algebraic equation 2x + 3y + z gives;
2(-2) + 3(-3) + 5 = -5
B) x - y gives;
-2 - (-3) = 1
C) 2(x + y)/z gives;
2(-2 - 3)/5 = -2
D) 3x² - 2x + 1
f(-2) = 3(-2)² - 2x + 1
f(-2) = 17
E) 3y(x + x² - y)
3(-3)(-2 + (-2)² - (-3))
-9 * 5 = -45
F) -z²(1 - 2x)/(y - x)
Thus;
-5²(1 - 2(-2))/(-3 - (-2))
= 625
