x^2 + 3x - 28 = 0;
(x + 7)(x - 4) = 0;
x + 7 = 0; x = -7;
x - 4 = 0; x = 4
x = {-7, 4}

(6x^2 – 25x – 10) ÷ (3x + 2)
= (6x^2/3x + 2) + (-25x/3x + 2) + (-10/3x + 2)
= 2x - 29/3 R. 28/3

4x^6(-10x^5 + 4)
= (4x^6)(-10x^5) + (4x^6)(4)
= 16x^6 - 40x^11

5 + 2^2 x 3 ÷ (5 - 2)

= 5 + 4 x 3 ÷ (3)

= 5 + 12 ÷ 3

= 5 + 4

= 9
