The first term is, <span> <span>c2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> +4c </span> its coefficient is <span> 4 </span>.
The last term, "the constant", is <span> -3 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -3 = -3</span>

Hello :
x²+x - 2 =0
a=1 b=1 c = -2
<span>The sum of the roots is : S = -b/a
</span>S = - 1/1 = -1
Answer:
x=13
Step-by-step explanation:
We are given the formula r = st. We evaluate each option to know the correct answer.
A.) S = r/t
r = st
B.) t = r/s
r = st
C.) s = t/r
r = t/s
<span>D.) r = ts
</span>r = st
Therefore, the correct answer among the choice given is option C. It is not equivalent to the formula.
