Answer:
What equation? Here’s a big tip for you, equations contain an ‘equals sign’ (‘=’) and something that they are equal to. I’m assuming your equation is:
ax2+bx+c=0
I’m going to use p and q for the roots of the equation as they are easier to type than α and β . Thus we have:
a(x−p)(z−q)=0⇒ax2−a(p+q)x+apq=0
Equating coefficients with our initial equation:
x1 : b=−a(p+q)⇒p+q=−ba
x0 : c=apq⇒pq=ca
Now p2+q2=p2+2pq+q2−2pq=(p+q)2−2pq
=(−ba)2−2ca
=b2a2−2ca
=b2−2aca2
Answer:
x=3.2 ft
Step-by-step explanation:
Just subtract them and take the square root.
(50x^2 + 250) -(40x^2 + 350) = x^2=10
x=3.2 ft
