Answer: 5(x +1.5)^2
10(x +1)^2
1/4(x +2)^2
3(x +5/6)^2
Explanation: When your desired form is expanded, it becomes ...
a(x +b)^2 = a(x^2 +2bx +b^2) = ax^2 +2abx +ab^2
This tells you the overall factor (a) is the leading coefficient of the given trinomial. Factoring that out, you can find b as the root of the remaining constant.
a) 5x^2 +15x +11.25 = 5(x^2 +3x +2.25) = 5(x +1.5)^2
b) 10x^2 +20x +10 = 10(x^2 +2x +1) = 10(x +1)^2
c) 1/4x^2 +x +1 = 1/4(x^2 +4x +4) = 1/4(x +2)^2
d) 3x^2 +5x +25/12 = 3(x^2 +5/3x +25/36) = 3(x +5/6)^2
Answer:
Reproducible
Explanation:
A conclusion of an experiment is accepted by scientific community when the same results can be obtained by repetition of experiment. Reproducible nature of results makes them scientifically acceptable. If the same result of an experiment cannot be obtained by some other scientists, the conclusion is considered to be affected by handling errors and other chance factors.
Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.
