solve it​

Answer 1

Answer:

Hey! Mate Here is your solution. Thanks

Answer 2

equation is

x^2+2x-143=0

We have to make the factors of (-143x^2)

⇒ x^2+2x-143=0

⇒ x^2+13x- 11x - 143=0

Taking out common term

⇒ x(x+13) - 11(x + 13)=0

⇒ (x+13) (x - 11)=0

If ⇒ (x+13) =0

⇒ x = -13\\

Or

⇒ (x - 11) = 0

⇒ x = 11
