x²+2x-12=0

Please step by step. Thank you

Solution

Consider the given quadratic equation

x²+2x-12=0

We can write the above equation as

( x + 1 )² - 1 - 12 = 0

( x + 1 )² - 13 = 0

( x + 1 )² = 13

Take square root on both sides, we get

( x + 1 ) = ± (13)

add - 1 on both sides , we get

x = -1 ± ( 13 )
