Find the value of "x" if a + 1 = 0 and 2x2 + ax - 3 = 0​

Answer 1

Hey, Hi!! I'm assuming in the second equation it's 2x². I'm solving the problem that way. Hope its right.

Answer:

x = -1 (or) 3/2

Step-by-step explanation:

Given,

a + 1 = 0 ---(1)

from (1)

a = -1

also given,

2x²+ ax -3 = 0 ---(2)

substitute a=-1 in (2)

2x²+ (-1)x -3 = 0

2x² -x -3 = 0

By factorisation,

(2x - 3) (x + 1) = 0

x = 3/2 (or) -1
