Answer: 49
Step-by-step explanation:
a=1 ,b=14, c=?
b^2-4ac =0
(14)^2-4(1)(c)=0
196-4c=0
196=4c
c=49
Check:
(x)^2+2(x)(7)+(7)^2
x^2+14x+49
(x+7)^2

The answer is "
".
Step-by-step explanation:
Given value:

They understand that, by using algebraic expressions laws, they subtract that inverse whenever we subtract powers with the same base. Every exponent's core is 2, therefore we subtract:

They have a shared denominator. It's least that is equally divided
among 8 or 2 is 8:


This gives us:

As rational notation is written as extremists, that root was its denominator as well as the power seems to be the numerator.
Which means 8 is the root and 5 the force that gives us:
