Answer 1

1
$2 {x}^{2} + 8x + x + 4 = 2 {x}^{2} + 9x + 4$
2
$10 {x}^{2} + 15x - 8x - 12 = 10 {x}^{2} + 7x - 12$
3
$6ax - 3x - 4a + 2$
4
$20 {a}^{2} - 5ab - 12ab + 3 {b}^{2} = 20 {a}^{2} - 17ab + 3 {b}^{2}$
5
$4 {m}^{2} - 10mn + 6mn - 15 {n}^{2} = 4 {m}^{2} - 4mn - 15 {n}^{2}$
6
$3 {x}^{2} - 3xy + 2xy - 2 {y}^{2} = 3 {x}^{2} - xy - 2 {y}^{2}$
7
$10 {b}^{2} - 10bc - 8bc + 8 {c}^{2} = 10 {b}^{2} - 18bs + 8 {c}^{2}$
8
$8 {p}^{2} + 5qp - 24qp - 15 {q}^{2} = 8 {p }^{2} - 19qp - 15 {q}^{2}$
