Answer:
no. f-1 does not equal to f.
Step-by-step explanation:
Step-by-step explanation:
Find the product, sum and factors which are P=56, S=15 and F=8,7 respectively.
r²+15r+56=0
replacing with the factors in the equation
=> r²+8r+7r+56=0
r(r+8)+7(r+8)=0
(r+8)(r+7)=0
=> r= –8 and –7
2/5= 40%, so no, they are not equivalent numbers,<span />
