Question

solve the following quadratic equation by completing square method X square + 2 x minus 5 is equal to zero​

Answer 1

Answer:

x=-1,x=-3

Step-by-step explanation:

x2+2x-5=0

*Third term = (1/2 ×coordinate of x)^2

=(1/2×2)^2

=1

add 1 on both sides

x2+2x-5+1=0+1

x2+2x-4=1

(x+2)^2=1

x+2=1,x+2=-1

x=1-2,x=-1-2

x=-1,x=-3
