Question

3a(a+b+c)-2b(a-b+c)from4c(-a+b+c)

Answer 1

Step-by-step explanation:

$4c( - a + b + c) - ((3a(a + b + c) - 2b(a - b + c))$

$- 4ca + 4bc + {4c}^{2} - (( {3a}^{2} + 3ab + 3ac - 2ba + {2b}^{2} - 2bc))$

$- 4ca + 4bc + {4c}^{2} - ((3 {a}^{2} + ab + 3ac - 2bc + {2b}^{2} ))$

$(- 4ca + 4bc + {4c}^{2} - {3a}^{2} - ab - 3ac + 2bc - {2b}^{2} )$

$(- 1ca + 6bc + 4 {c}^{2} - {3a}^{2} - ab - {b}^{2} )$
