Question

(x-1)²=2x+3 find a,b,c
find a,b,c using Quadratic equation formula
​

Answer 1

Answer:

If (x-1)²=2x+3  then a = 1, b = - 4 and c= - 2

Step-by-step explanation:

Given: (x-1)²=2x+3

Find a, b, c

(x-1)²=2x+3

x² - 2x + 1² = 2x + 3

x² - 2x + 1 = 2x + 3

x² -2x - 2x + 1 - 3 =0

x² - (2 + 2)x + (1 -3) =0

x² - 4x - 2 = 0

Compare with ax² + bx + c = 0

So, a = 1, b = - 4 and c= - 2
