Answer:
x= -7 x = -1
Step-by-step explanation:
x^2 + 8x + 7 = 0
Factor
What 2 numbers multiply to 7 and add to 8
7*1 = 7
7+1 = 8
(x+7)(x+1) =0
Using the zero product property
x+7 =0 x+1 = 0
x= -7 x = -1
Factor
x(2x-1)=0
x = 1/2, 0
Cross multiply to find your answer
x/250 = 20/100
250 X 20= 5000
5000=100x
x = 50
250 - 50 = 200
4x - 10 = 34
4x +10 +10
4x = 44
4x/4 = 44/4
x = 11
