Find the solution(s) of the quadratic equation x2 + 2x -15 = 0. A)x= -5,3
B)x= 5,3
C)x= -5 -3
D)x= 5,-3

The answer is A.

Step-by-step explanation:

Let's solve your equation step-by-step.

x2+2x−15=0

Step 1: Factor left side of equation.

(x−3)(x+5)=0

Step 2: Set factors equal to 0.

x−3=0 or x+5=0

x=3 or x=−5

x=3 or x=−5

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
