Answer:
-21x^2+50x-24
Step-by-step explanation:
3x((5)(2)-7x+2)-2((5)(2)-7x+2)
30x-21x^2+6x-20+14x-4
50x-21x^2-24
-21x^2+50x-24
Answer:
let the two numbers are x & y
x+y=30...eq(1) &x-y=12....eq(2)
x=30-y then put in the eq(2)
30-y-y=12
30-2y=12
-2y=12-30
-2y= -18
y=9 then we put this answer in to eq(1)
so,x+y=30
x+9=30
x=30-9
x=21
so, the two numbers are (21,9)
