(u+v)*2+2(u+v)-3<br>factorise it completely <br>it's a challenge <br><br><br>​
lions [1.4K]

If you mean

(u+v)^2+2(u+v)-3

you can first substitute x=u+v to get

x^2+2x-3=(x+3)(x-1)

and so

(u+v)^2+2(u+v)-3=\boxed{(u+v+3)(u+v-1)}

1. Un examen de Matemáticas ha sido aprobado por 6/9 de los estudiantes. Al resto de los estudiantes le toca repetir el examen.
Eddi Din [679]

Answer:

15 students

Step-by-step explanation:

The fraction of students who will repeat the exam is:

1-\frac{6}{9}

=\frac{9}{9} -\frac{6}{9} =\frac{3}{9}

simplified is:

\frac{1}{3}

Extract this fraction of 45:

45(\frac{1}{3} )=\frac{45}{3} =15

Hope this helps
