-2x^2 - 3x + 2 = 0 (move the segment)

0 = 2x^2 + 3x - 2

2x^2 + 4x - x - 2 = 0

2x(x + 2) - (x + 2) = 0

(x + 2)(2x - 1) = 0

a = x1 = -2
b = x2 = 1/2


[tex]a ^{2} b + ab ^{2} [/tex]
[tex] = ( - 2) ^{2} \times \frac{1}{2} + - 2( \frac{1}{2} ) ^{2} [/tex]
[tex] = 4 \times \frac{1}{2} + - 2 \times \frac{1}{4} [/tex]
[tex] = 2 + - \frac{2}{4} [/tex]
[tex] = \frac{8}{4} - \frac{2}{4} [/tex]
[tex] = \frac{6}{4} [/tex]

[tex] = \frac{3}{2} [/tex]
[tex](d)[/tex]
