Multiply by the opposite by using the difference of squares converse formula.
Complete the equivalent equation for –7x<span> – 60 = </span>x2<span> + 10</span>x.
(x<span> + 5</span>)(x<span> + 12) = 0</span>
What are the solutions of –7x<span> – 60 = </span>x2<span> + 10</span>x?
x<span> = -12 or -5</span>

The reason why Maria's experimental probability may be different from the theoretical probability of spinning a coin is because the theoretical is when you do not have the exact answer, which you kind of guess, while the experimental probability, you find out the exact answer of the problem.
Experimental probability: 62/100 of heads and 38/100 of tails
Theoretical probability: 50/100 of heads and 50/100 of tails (Since a coin only has two sides, which is heads and tails, the chance might be 50% of heads and 50% of tails.)
