Question

(n-45)²+1975, what is the value of n?

Answer 1

${n}^{2} + {45}^{2} - 2 \times n \times 45 + 1975 = 0$
${n}^{2} + 2025 - 90n + 1975 = 0$

Answer 2

{n}^{2} + {45}^{2} - 2 \times n \times 45 + 1975 = 0n2+452−2×n×45+1975=0 
{n}^{2} + 2025 - 90n + 1975 = 0n2+2025−90n+1975=0 
this, is your answer
