Question

product of (5x-y+z)(5x-y+z)​

Answer 1

Answer:

$\large{ \bold{25 {x}^{2} + {y}^{2} + {z}^{2} - 10xy - 2yz + 10xz}}$

Step by step

${(5x - y + z)(5x - y + z)} \\ \\ = {(5x - y + z)}^{2} \\ \\ = 25 {x}^{2} + {y}^{2} + {z}^{2} - 10xy - 2yz + 10xz \\ \\ \\ \\ formula \\ \\ (a + b + c)^{2} = {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ca$
