Mathematics

zaharov [31]3 years ago

We must find the common denominator.

LCM(6, 3) = 6

5\dfrac{1}{6}-1\dfrac{1}{3}=5\dfrac{1}{6}-1\dfrac{1\cdot2}{3\cdot2}=5\dfrac{1}{6}-1\dfrac{2}{6}=(5-1)+\left(\dfrac{1}{6}-\dfrac{2}{6}\right)=4-\dfrac{1}{6}=3\dfrac{5}{6}

or other method of calculating the difference

5\dfrac{1}{6}-1\dfrac{2}{6}=4\dfrac{6+1}{6}-1\dfrac{2}{6}=4\dfrac{7}{6}-1\dfrac{2}{6}=(4-1)+\left(\dfrac{7}{6}-\dfrac{2}{6}\right)=3\dfrac{5}{6}

What is the factorization of the following trinomial? 15x2 - 44x - 36
BartSMP [9]
15x^2-44x-36

=(15x^2+10x)+(-54x-36)

factor out  5x from 15x^2+10x  = 5x(3x+2)

Factor out -18 from -54x-36 =  -18(3x+2)

=5x(3x+2)-18(3x+2)

Factor out common term (3x+2)

= (3x+2)(5x-18)

hope this helps!
