Question 818084: hello,
Please help me solve these two problems, I got about half way through them and I got stuck.
1. solve by factoring 4w^2-25=0
2. Solve by Quadratic formula
3/4(x^2)-2+3/4=0
Thank you so much for your help

1. solve by factoring
4w^2-25=0
(2w-5)(2w+5)=0
so either 2w-5=0
or2w+5=0
2w-5=0
2w=5
w=5/2
2w+5=0
2w=-5
w=-5/2
w=+/- 5/2

2. Solve by Quadratic formula
3/4(x^2)-2x+3/4=0

a= 0.75 , b= -2 , c= 0.75

b^2-4ac= 4 + -2.25
b^2-4ac= 1.75

x1=( 2 + 1.32 )/ 1.5
x1= 2.22

x2=( 2 -1.32 ) / 1.5
x2= 0.45
