Question

(m2 + 14m +31) = (m + 10)

Answer 1

M = -7/5

Explanation:

(m2 + 14m +31) = (m + 10)

14 + 2

16m+31=m+10

Subtract 31 from both sides

16m + 31 - 31 = m + 10 - 31

Simplify

16 = m -21

Subtract m from both sides

16m - m = m - 21 - m

Simplify again

15m = -21

Divide both sides by 15

15m/15 = -21/15

Simplify last

M = -7/5

Decimal form: M = -1.4
