Since we are multiplying two equations, we will distribute the terms:
(0.1x - 1.2y)(0.1x + 1.2y)= 0.1x 0.1x + 0.1x 1.2y - 1.2y 0.1x - 1.2y 1.2y= 0.01x^2 + 0.12xy - 0.12xy - 1.44y^2= 0.01x^2 - 1.44y^2
Therefore, (0.1x - 1.2y)(0.1x + 1.2y) simplifies to 0.01x^2 - 1.44y^2.
Since we are multiplying two equations, we will distribute the terms:
(0.1x - 1.2y)(0.1x + 1.2y)
= 0.1x 0.1x + 0.1x 1.2y - 1.2y 0.1x - 1.2y 1.2y
= 0.01x^2 + 0.12xy - 0.12xy - 1.44y^2
= 0.01x^2 - 1.44y^2
Therefore, (0.1x - 1.2y)(0.1x + 1.2y) simplifies to 0.01x^2 - 1.44y^2.
