What To Do
Let x be the number
Use a variable to represent the
unknown
+ 15
Translate into mathematical
expression
Place polynomial on one side and
set equation to zero by Additive
Inverse Property
x² + 15 -
= 8x -
2 + 15 - 8x
=
Write the resulting equation
x2
8x +
=
Arrange the terms in descending
order of its exponents
()()
= 0
Factor the polynomial
(X - _) = 0 or (x –
-) = 0
Apply the Zero Property
x- 5 + - = 0+ -
OT
