X (exponent 2) + 7x+6 quadratic formula

Next time, use the carrot for exponent like this:

x^2+7x+6=0

The first term is a, the second is b and the last is C

Quadratic is ax^2+bx+c=0

The formula is - (b) + - squareroot (b^2 - 4 (a) (c)) all over two a

So youve got:

-7 + - square root (49-4 (1) (6)) divided by 2 (1)

Simplify

-7 + - squareroot (49-24) / 2

-7 + - square root (25) / 2

25 is a perfect square of five, so tou have

(-7 + 5) / 2 And (-7-5) / 2

You answers should be : - 1 & - 6

X² + 7x + 6 = 0

x = - (7) + / - √ ((7) ² - 4 (1) (6))

2 (1)

x = - 7 + / - √ (49 - 24)

2

x = - 7 + / - √ (25)

2

x = - 7 + / - 5

2

x = - 7 + 5 x = - 7 - 5

2 2

x = 2 x = - 12

2 2

x = 1 x = - 6

The solution is equal to {1, - 6}.
