Question

x^2+6x-7=0 splve by quadratic formula​

Answer 1

Step-by-step explanation:

Here,

x² + 6x - 7 = 0

x² -7x + x - 7 = 0

x( x - 7) + 1( x - 7) = 0

( x - 7) ( x + 1) = 0

Either,

x - 7 = 0

x = 7

or,

x + 1 = 0

x = -1 ans

Answer 2

$x^2+6x-7=0\\\\x^2-x+7x-7=0\\\\x(x-1)+7(x-1)=0\\\\(x+7)(x-1)=0\\\\x=-7\\\\and\\\\x=1$
