Question

find the root of the following equation X square + 2x-5 is equal to zero​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Roots: -3.449 and 1.449

or -1 ± √(6)

Step-by-step explanation:

X² + 2x-5 =0

root of a quadratic equation ax²+bx+c is given by

{ ${-b +\sqrt{b^{2} -4ac } }$ } /2a    and {   -b - $\sqrt{b^{2} - 4ac }$ }

for our equation

a=1 , b=2 , c-= -5

the roots would be "

Roots: -3.449 and 1.449

Root Pair: -1 ± √(6)
