Find the greatest common factor of the monomials.

20x², 36x =

Answers

Answer:

i think its -4

Step-by-step explanation:

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

-4.

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

Ignore the factor -4. ._.

While some view these gardens as hands-on learning opportunities, others view the gardens as taking time away from classroom academics. Opponents to school gardens say that students need rigorous classroom teaching in order to be successful adults. Gardening is something adults typically do in their free time as a hobby, not as work. Those against school gardens say that schools should not teach a hobby during work hours. Finally, opponents say that research does not provide any proof that time spent in a schools garden leads to higher graduation rates.Supporters of school gardens say that these gardens allow students to apply what they are learning in class to the real world. Students have to problem solve, and work together. Students apply the skills they are learning in science and math in the garden. No other experience can provide a natural laboratory for students to explore living things and the environment. Nearly every research study for the past 100 years has shown that for students to perform well after graduation, schools must teach to the whole child and provide whole-school experiences."
