X²-10x+25=0 quadratic equation by factoring

lisov135 [29]

Answer:

x = 5

Step-by-step explanation:

${x}^{2} - 10x + 25 = 0 \\ {x}^{2} - 5x - 5x + 25 = 0 \\ x(x - 5) - 5(x - 5) = 0 \\ (x - 5)(x - 5) = 0 \\ ( x- 5) = 0 \: or \: (x - 5) = 0 \\ x = 5 \: or \: x = 5 \\ x = 5$

Our math team had m students last year, but this year it has already n students! By what percent did the number of students grow

AlekseyPX

For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
$(n / m) * 100 - 100$
Answer:
the number of students did grow by:
$(n / m) * 100 - 100$
