X+y=34
xy=128
let the first number=17+h
second number=17-h

product=(17+x)(17-x)
128=289-h²
289-128=h²=168
h=√168
numbers=17+√168=x=29.961481397
y=17-√168=4.038518603

is this is a perfect ans
ya
u know it very wel ths is my exam ques

x = 34 - y
so substitute x value in product form:
(34-y) y = 128
34y - y² = 128
y² - 34y + 128 = 0

=

=

=

=

=17 pm √161

y = 17 + √161 or 17 - √161

x =34-y
=34-17-√161
= 17-√161 or 17 +√161
tysm
cant understand
pm...indicates..+ or -
this is a formula to find the value of x in 2nd degree
