Answer: First option
Step-by-step explanation:
You have the quadratic equation given in the problem:
To find an equivalent expression you cacn factorize. Find two numbers whose sum is -13 and whose product is -30.
These numbers would be -15 and 2.
Therfore, you obtain the following equivalent expression:
If you don't want to apply the method above, you can use the quadratic formula:
Where:
When you susbstitute values you obtain that:
Then you can rewrite the equation as
add 2 to both sides
square both sides
3x-5=4
add 5 to both sides
3x=9
divide 3
x=3
