Answer:
<h2>
(2m-7)(m+3)</h2>
Step-by-step explanation:
hello:
2m² - m - 21
∆ =b²-4ac a=2 and b= -1 and c= -21
∆ =(-1)²-4(2)(-21)=169 = 13²
m1 = (-b+√∆)/2a = (1+13)4 = 14/4 = 7/2
m2 = (-b-√∆)/2a = (1-13)4 = -12/4 = -3
the factorization is : a(m-m1)(m-m2)
2(m-7/2)(m+3) = (2m-7)(m+3)
R(s + t) = st
Rs + Rt = st
Rs - st = -Rt
s ( R - t) = -Rt
*s = - Rt / (R - t) Multiply through by -1 on the right.
*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means
s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.
