Pedro and Rebecca were trying to solve the equation: 0.1x^2-0.7x+1.2=0. Pedro said, “I can multiply the entire equation by 10 and then factor. Then I can solve using the zero product property.” Rebecca said, “I'll solve using the quadratic formula with a=0.1, b=-0.7, c=1.2.” Whose solution strategy would work?

Both methods will work, but Rebecca's one is harder than Pedro's method.

Whose solution strategy would work?

Pedro wants to multiply the whole equation by 10, so he can work with whole numbers which is easier, while Rebecca prefers to just use Bhaskara's formula with the given coefficients.

With that in mind, neither method has a problem, so both will work fine. The only problem that could come is that for Rebbeca, when she wants to evaluate the square root in the Bhaskara's formula, she will get:

[tex]\sqrt{(-0,7)^2 - 4*0.1*1.2 } = \sqrt{0.01}[/tex]

And that is kinda impossible to compute by hand, but if she has a calculator, everything is fine.

Then we conclude that both methods will work.
