Question

How to factor this equation w^2+18w+77

Answer 1

w^2+11w+7w+77 from here solve it

Answer 2

you need two numbers which when multiplied together give 77 and when add give 18
these are 7 and 11
so factors are (x + 7)(x + 11)

Answer 3

w^2+11w+7x+77
= w(w+11)+7(w+11)
(w+7)(w+11)

Answer 4

either x+7 = 0 or x+11 = 0
so roots are -7,-11

Answer 5

oh sorry - replace x by w!!!

Answer 6

soooo its neg instead of pos . ?

Answer 7

the roots of the equation (w+7)(w+11) = 0 are negative
as
w + 7 = 0
subtract 7 from both sides
w +7 - 7 = 0-7
w = -7
same thing for w+11

Answer 8

you called (w+7)(w+11) an equation - its not - its a function of w
(w+7)(w+11) = 0 is an equation

Answer 9

in order to solve it you factor it first
