Question

Using proper identities solve for : (x - 5)^2​

Answer 1

Answer:

x^2+25-10x

Step-by-step explanation:

(a-bj^2=a^2 + b^2 -2ab

therefore,

(x-5)^2= x^2+25-10x

Answer 2

${(x - 5)}^{2} \\ using \: identity - \\ {(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2} \\ {(x - 5)}^{2} \\ = {x}^{2} -2 \times x \times 5 + {5}^{2} \\ = {x}^{2} - 10x + 25$
