Question

5x^2+2x-3=0 by factorisation method​

Answer 1

X= -1 or X=3/5

Explanation:

5x^2+2x-3=0

(x+1)(5x-3)=0

x= -1 or 5x/5=3/5

x=3/5

Answer 2

x = - 1, 0.6

Explanation:

`5 {x}^(2) + 2x - 3 = 0 \\ \\ 5 {x}^(2) + 5x - 3x - 3 = 0 \\ \\ 5x(x + 1) - 3(x + 1) = 0 \\ \\ (x + 1)(5x - 3) = 0 \\ \\ x + 1 = 0 \: \: or \: 5x - 3 = 0 \\ \\ x = - 1 \: \: or \: \: x = (3)/(5) \\ \\ x = - 1 \: \: or \: \: x = 0.6 \\ \\ x = - 1, \: \: 0.6`
