First we need to find delta for function ax2+bx+c = 0
DELTA = b2-4ac
DELTA = 25 -( 4*1*5)= 25 - 20 = 5
x1 = (-b-√DELTA)/2a = (-5 - √5)/2
x2 = (-b+√DELTA)/2a (-5+√5)/2
x1 and x2 are zeros of this function
Can I see ur questions so I can help
56/128
Simplify
28/64 - 14/32 - 7/16
7/16 = x/100
Cross multiply
700 = 16x
x=43.75
43.75%
