(x+1)²=2(x-3)
Asked by Kunalbaniya384 | 25 Nov, 2023, 08:32: PM
Expert Answer
( x+1)2 = 2 (x-3)
x2 + 2x + 1 = 2x - 6
x2 +7 = 0
If we compare above expression with standatrd quadratic equation " ax2 + bx + c = 0 ",
we get a =1 , b = 0 c = 7.
Discriminant D = b2 - ( 4 a c ) = -7
Since discriminant ( b2 - 4 a c ) < 0 , above equation does not have real solution.
