Answer:
x = -1 and x= 14
Step-by-step explanation:
x^2 -13x -14=0
x^2 + x- 14x -14 = 0
x(x+1) -14(x+1) = 0
(x+1)(x-14) =0
x+1 = 0
x= -1
x-14=0
x= 14
Answer:6
Step-by-step explanation:
*we solve every bracket alone
-(√2+1)² = [rule:1st *1st + 2*1st*2nd + 2nd*2nd]
2+2√2+1
3+2√2
-(√2-1)= [rule:1st*1st - 2*1st*2nd + 2nd+2nd]
2-2√2+1
3-2√2
-we write the whole equation
3+2√2+3-2√2 (+2√2 - 2√2) {positive and negative remove each other}
3+3=6

Theres a website called spades (or something like that) if you go on it look for your math text book and it will have the answers for you
I think so:
