Question

Factor 1 - 2.25x8.
(1 - 1.5x4)2
(1.5 + x4)(1.5 - x4)
(1 + 1.5x4)(1 - 1.5x4)

Answer 1

\((a^2-b^2)=(a+b)(a-b)\)
What are a and b in this problem?

Answer 2

1 and 2.25

Answer 3

Where's the x? Put them in terms of something squared. So if it was \(x^2-9\) a would be x, and b would be 3, so it would be \(x^2-3^2\)
