One of the solutions to x2 − 2x − 15 = 0 is x = −3. What is the other solution?
2 answers:
<span>x2 − 2x − 15 = 0
</span>(x+3)(x-5) = 0
x +3 = 0 so x = -3
x - 5 = 0 so x = 5
answer is <span>d.x = 5</span>
Answer:
x=5
Step-by-step explanation:
One of the solutions to
is x = −3
To find out the other solution, we factor the x^2-2x-15
Product is -15 and sum is -2


So factors are -5 and 3


we set each factor =0 and solve for x


other solution is x=5
