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 1, b = -0.7 and c = 1.2"
WHOs Strategy works?
A - Only Pedro's
B - Only Rebecca's
C - Both
D - Neither

The correct strategy between Pedro and Rebecca trying to solve the quadratic equation: 0.1x^2 - 0.7x + 1.2 = 0 is A - Only Pedro'sHow to determine the correct strategyThe given function is a quadratic function which is solved by several method including the method both Pedro and Rebecca are trying to usePedro's method is the factorization method and the steps mentioned are correct However Rebecca's method has some errorThe equation is: 0.1x^2 - 0.7x + 1.2 = 0factor of the leading coefficient a is 0.1, Rebecca is using 0.11The error of using 0.11 instead of 0.1 will make the method ineffectiveLearn more about quadratic equations here:https://brainly.com/question/29116024#SPJ1
