Answer:
x = -10, x=5
Step-by-step explanation:
x^2 +5x - 50 = 0
What two number multiply to -50 and add to 5
10 * -5 = -50
10 + -5 = 5
( x+10) (x-5) =0
Using the zero product property
x+10 =0 x-5 =0
x+10-10 =0-10 x-5+5=0+5
x= -10 x =5
Question B) you want to take 0.75, divide it to both sides and you get m= 21 0.75m=15.75 m = 21 ___________ = 0.75
Decimal - 1.6 fraction - 1 3/5
