Answer 1

Answer:

see all of them are quadradic equations . QUADRADIC EQUATION are equations in which the X has a degree of 2 . hence, a term with variable as

$x {}^{2}$

Answer 2

Step-by-step explanation:

By splitting the middle term

1) x^2 + 5x - 14 = 0

Therefore,

-14 = +7*-2

And +7-2= 5

Therefore,. x^2+ 5x-14 = 0

x^2 -2x + 7x -14 = 0

x ( x-2 ) + 7 ( x - 2 ) = 0

(x+7) ( x-2)= 0

therefore,

x+7 = 0. & x-2 = 0

x = -7 x = 2
