Answer 2

Answer:

2.

(i) 3x - 5a -x² + 9b(putting all values)

= 3(-3) - 5(-2) - (-3)² + 9(-5)

= -9 - (-10) - 9 + (-45)

= -9 + 10 -9 - 45 = 10 -63 = -53

(ii) 2b - 8x + 4x²+ 4a

= 2(-5) - 8(-3) + 4(-3)² + 4(-2)

= -10 + 24 + 36 +(-8)

= 60-18 = 52

(iii) 3a + 5 - 8x + 1

= 3(-2) + 5 -8(-3) +1

= -6 +5 +24 +1 = 24

(iv) 10x -3b - 4a -5b²

= 10(-3) -3(-5) -4(-2) -5(-5)²

= -30 +15 +8 -125 = -132
