Answer 1

Answer:

Here is your answer friend

Step-by-step explanation:

first

Using

$(a + b + c) = {a}^{2} + {b}^{2} + {c}^{2} \times ab + 2 \times ac + 2 \times bc$

expand the expression

$( - 2 {a}^{2}) + (5 {b}^{2} ) + ( - {3c}^{2} ) + 2x( - 2)a \times 5b + 2( - 2)a \times 5b + 2( - 2)a( - 3)c + 2 \times 5b( - 3c)c$

after that solve the equation:-

${4a}^{2} + {25b}^{2} + {9c}^{2} - 20ab + 12ac - 30bc$

that's your answer
