The given equation is,
-5x³ + 3x² - 8x + 2
Substituting the value of x in the above equation, we have
= -5(-2)³ + 3(-2)² - 8(-2) + 2
= 40 + 12 + 16 + 2
= 70
Hence on substituting the given value of x in the equation, the resultant answer is 70.

x = -8
x = -1.2, y = -3
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
x=35
You find x. Oh! There it is!! ^ See?
172=x
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x+y=-7 3x+y=15 8=D
