Answer: -15 and 2</h3>
You find this through trial and error.
A much more efficient way is to solve x^2-13x-30 = 0 using the quadratic formula. You'll find the two solutions to be x = 15 and x = -2
Going from those solutions, we get x-15 = 0 and x+2 = 0 which then turn into (x-15)(x+2) = 0 through the zero product property.
If you move it to the left the number would increase so for example you had 2.3 and you move it to the left then it would be 23, so if you times it by tenth or hundredth then it would go to the left but if you divide then it would go down so moving to the right would get you 0.23
Ax + b = r
subtract ax from both sides:-
ax - ax + b = r - ax
b = r - ax (answer)
Answer:
72x56x267 then put those together and you get the answer
Answer:
x = 3 and x = -3 (aka. x = ±3)
Step-by-step explanation:
2x² - 18 = 0
x² - 9 = 0
x² = 9
x = ±3
Therefore, x = 3 and x = -3
