Using factoring, which values are the solutions to the quadratic equation 2m2+7m−30=0?
Luden [163]

Answer:

B: m = -6 or m = 5/2

Explanation:

\rightarrow \sf 2m^2 +7m - 30 = 0

<u>breakdown</u>

\rightarrow \sf 2m^2 +12m -5m- 30 = 0

<u>take out common factor</u>

\rightarrow \sf 2m(m +6) -5(m+ 6) = 0

<u>collect into groups</u>

\rightarrow \sf (2m -5)(m+ 6) = 0

<u>set to zero</u>

\rightarrow \sf 2m -5=0, \ m+ 6 = 0

<u>change sides</u>

\rightarrow \sf m=2.5, \ m= -6
