Question

.
Find the roots of the Quadratic equation equation xsquare+ 2x - 3= 0.
​

Answer 1

Answer: -3,1

Step-by-step explanation:

x² + 2x - 3 = 0

Sum = 2

Product = -3

The numbers are 3,-1

x² - x + 3x - 3 = 0

x(x-1) + 3(x-1) = 0

[x+3][x-1] = 0

x+3 = 0..... x = -3

x-1 = 0...... x = 1

Answer 2

Given

X2 + 2X - 3 = 0

a = 1 b = 2 c = -3

sum of two zeroes = -b/a = -2/1 = -2

product of two zeroes = c/a = -3/1 = -3

The numbers are 3 , -1

X2 + 2X - 3 = 0

X ( X - 1 ) + 3 ( X - 1 ) = 0

( X - 1 ) ( X + 3 ) = 0

X - 1 = 0 | X + 3 = 0

|

X = 1 | X = -3

the numbers are 1 and -3
