Which equation has the same solutions as 2 times ex squared plus ex minus 3 equals 0?

Question

Which equation has the same solutions as ?

Answer 1

This is a tricky problem, because its "same solutions as" implies that there's another equation besides the 2x^2 + x - 3 = 0 given. Factoring the left side will give you values of 1 and -1.5 for x. If you take these values and put them back as factors and multiply, you'll get an equation that's different from the original.

Answer 2

2x^2 + x-3= 0

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

2x+3 = 0

x = -3/2

x-1 = 0

x = 1

x= 1 or -1.5
