If 5a2+b2+ c2- 6a-8c 4ab -25, then the value of (b- c2+a) is

1.	If 5a2+b2+ c2- 6a-8c 4ab -25, then the value of (b- c2+a) is
Answer» SOLUTION GIVEN $\sf{5 {a}^{2} + {b}^{2 } + {<klux>C</klux>}^{2} - 6a - 8c = 4ab - 25 }$ TO DETERMINE The VALUE of $\sf{b - {c}^{2} + a}$ EVALUATION Here the given EXPRESSION is $\sf{5 {a}^{2} + {b}^{2 } + {c}^{2} - 6a - 8c = 4ab - 25 }$ Now we SIMPLIFY it as below $\sf{5 {a}^{2} + {b}^{2 } + {c}^{2} - 6a - 8c = 4ab - 25 }$ $\sf{ \implies \: 5 {a}^{2} + {b}^{2 } + {c}^{2} - 6a - 8c - 4ab + 25 = 0 }$ $\sf{ \implies \: 4 {a}^{2} - 4ab + {b}^{2 } + {c}^{2} - 8c + 16 + {a}^{2} - 6a + 9 = 0 }$ $\sf{ \implies \: {(2a - b)}^{2} + {(c - 4)}^{2} + {(a - 3)}^{2} = 0 }$ Which gives 2a - b = 0 , c - 4 = 0 , a - 3 = 0 Thus we get a = 3 , b = 6 , c = 4 Hence $\sf{b - {c}^{2} + a}$ $\sf{ = 6 - {(4)}^{2} + 3}$ $\sf{ = 6 - 16 + 3}$ $= - 7$ ━━━━━━━━━━━━━━━━ Learn more from Brainly :- 1. solve: 49³-30³+(...)³= 3 × 49 × 30 × 19 brainly.in/question/17577612 2.
