Algebra I

posted by .

I can understand this if the steps are shown to me. Please help me explain it to my daughter!

One number is 8 more than another number. Their product is 273.

I got this far.

X(X + 8) = 273

X^2 + 8X = 273

• Algebra I -

Factor 273 into prime factors: 3 * 7 * 13. What combination of factors would give a difference of 8? In this case, it would be 21 and 13.

If you want to use the equation:

X^2 + 8X - 273 = 0

(X + 21)(X -13) = 0

X = 13

X = I-21I (absolute value)

I hope this helps. Thanks for asking.
