Question

Write the equation in standard form
${(x - 1)}^{2} = 2x + 3$
​

Answer 1

Answer:

x² - 4x - 2 = 0

Step-by-step explanation:

( x - 1 )²

Formula : -

( a - b )² = a² + b² - 2ab

Here,

a = x

b = 1

( x - 1 )² = x² + 1 - 2x

( x - 1 )² = 2x + 3

x² + 1 - 2x = 2x + 3

x² + 1 - 2x - 2x - 3 = 0

x² - 2x - 2x + 1 - 3 = 0

x² - 4x - 2 = 0
