Verify that −1+2i and −1− 2i are solutions to x²+2x+5=0.

NO

Step-by-step explanation:

Given

Quadratic equation

First we need to check discriminant of equation to know whether roots are real of imaginary

here

a=1, b=2, c=5

thus D<0 therefore roots are imaginary

To verify given roots are roots of equation

sum of roots

Product of roots

-2=-2

L.H.S=R.H.S

Product of roots

thus given values are not solutions of given equation.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
