Question

plz do these sums....​

Answer 1

$\huge\bold\orange{Answer:}$

$\textbf{\underline{\underline{Answer\:1:}}}$

$( \sf {a}^{2} - 3a + 4)(a - 3)$

$\sf \: a( {a}^{2} -3a + 4) - 3( {a}^{2} - 3a + 4)$

$\sf {a}^{3} - 3 {a}^{2} + 4a - 3 {a}^{2} + 9a - 12$

$\sf { a}^{3} -6{a}^2 + 13a - 12$

$\textbf{\underline{\underline{Answer\:2:}}}$

$\sf ( m + 2p)(m - 3p)$

$\sf \: m(m - 3p) + 2p(m - 3p)$

$\sf \: {m}^{2} - 3pm + 2pm - 6 {p}^{2}$

$\sf {m}^{2} - pm - 6 {p}^{2}$

$\textbf{\underline{\underline{Answer\:3:}}}$

$\sf \: ({x}^{2} - 2x + 3)(x - 2)$

$\sf \: x( {x}^{2} - 2x + 3) - 2( {x}^{2} - 2x + 3)$

$\sf \: {x}^{3} - 2 {x}^{2} + 3x - 2 {x}^{2} + 4x - 6$

$\sf {x}^{3} - 4 {x}^{2} + 7x - 6$

$\textbf{\underline{\underline{Answer\:4:}}}$

$\sf \: - 4m(2m - 5n)$

$\sf \: - 8 {m}^{2} + 20mn$
