Question

x^2-2x-35=0 use the quadratic formula to solve the equation

Answer 1

...so use the quadratic formula...what's the problem?

Answer 2

This is in the form \(y = ax^2 + bx + c\).
THis is the quadratic formula:
\[x = \frac{-b ± \sqrt{b^2 - 4ac}}{2a}\]Plug in a, b, and c based on the first thing I said.

Answer 3

i dont know how to solve

Answer 4

Literally, just plug in numbers and simplify...
\[x = \frac{2 ± \sqrt{(-2)^2 - 4(1)(-35)}}{2(1)} \implies?\]

Answer 5

ok

Answer 6

What do you get?

Answer 7

10/2

Answer 8

THat's one. What about the other?
\[x = \frac{2 ± 12}{2} \implies x = 1 ± 6\]

Answer 9

So what are your two answers now?

Answer 10

sorry
