Answer:
[tex]3(2a {} + 3b + 4c) {}^{2} [/tex]
Step-by-step explanation:
[tex](2a + 3b + 4c) {}^{2} + (2a + 3b + 4c) {}^{2} (2a + 3b – 4c) {}^{2} [/tex]
[tex] = 4 {a}^{2} + 9 {b}^{2} + 16 {c}^{2} + 4 {a}^{2} + 9 {b}^{2} + 16 {c}^{2} + 4 {a}^{2} + 9 {b}^{2} + 16 {c}^{2} [/tex]
[tex]12 {a}^{2} + 27 {b}^{2} + 48 {c}^{2} [/tex]
[tex]3(4 {a}^{2} + 9 {b}^{2} + 16 {c)}^{2} [/tex]
[tex]3(2 {a}^{} + 3b + 4c) {}^{2} [/tex]
Hope this helps you
