Question

:- 2x²+ 13x +15=0
method and
by factorisation
​

Answer 1

Answer:

x=-3/2 and x=-5

Explanation:

$2 {x}^{2} + 13x + 15 = 0 \\ solve \: by \: factor \\ (2x + 3)(x + 5) \\ using \: zero \: factor \: principal \\ if \: ab = 0 \: then \: a = 0 \: or \: b = 0 \: \: or \: both \\ \\ solve \: 2x + 3 = 0 \: and \: x + 5 = 0 \\ x = - \frac{3}{2 } \: \: and \: x = - 5$
