Question

multiply (u+1) (u-5)

Answer 1

(a+b)(c+d)
a(c+d)+b(c+d)
use distributive property

Answer 2

\((\overbrace{\overbrace{\color{orange}a
+\underbrace{\color{cornflowerblue}b)(\color{seagreen}c}_{\text{Inside}}}^{\text{First}}
+\color{brown}d}^{\text{Outside}})
=\overbrace{\color{orange}a\color{seagreen}c}^\text F
+\overbrace{\color{orange}a\color{brown}d}^\text O
+\underbrace{\color{cornflowerblue}b\color{seagreen}c}_\text I
+\underbrace{\color{cornflowerblue}b\color{brown}d}_\text L\\
\qquad\quad \underbrace{\qquad\qquad}_{\text{Last}}\)

Answer 3

I don't understand , so its u(u-5) + 1(u-5) ? @myininaya

Answer 4

yes @Kb1997

Answer 5

I got u^2-5u+1?? @myininaya

Answer 6

so u(u-5)=u^2-5u right?
and 1(u-5)=u-5
so add those two together
that is add u^2-5u and u-5
u^2-5u+u-5=?

Answer 7

4u?

Answer 8

u^2-5u+u-5
-5u and u are the only like terms you got there
-5u+u is not 4u
but is it ?

Answer 9

-5+1=-4
so
-5u+1u=-4u right?
so you have
u^2-5u+u-5
=
u^2-4u-5
