## BMI229 multiples of 90 that add up to 24 10 months ago 10 months ago

I think you are looking for "factors" not "multiples"

2. AriPotta

i don't believe there are any...

3. BMI229

no im looking for multiples

4. 4kec4

i can only think of 18*5=90 but it adds up to 23.

5. electrokid

you are missing the signs too!!! multiples are greater than the number itself 90*1, 90*2, 90*3 , etc those are called multiples of 90

Solve for x: x2 + 24x + 90 = 0

8. electrokid

then you've got to use the quadratic equation. since there are so factors of +90 that add up to +24

Solving for x, and setting the equation to zero then i get two solutions: $x=3 (-4 - \sqrt{6})$ and $x=3 (-4 + \sqrt{6})$

11. BMI229

Solve for x: x2 + 24x + 90 = 0

you can't solve it by factoring, you gotta use that formula
