What are the solutions to this quadratic equation x2+6x-5=0
marishachu [46]

Answer:

See Below.

Explanation:

Quadratic Form:

a {x}^{2}  + bx + c

Quadratic Formula:

x =  \frac{ - b +   -  \sqrt{ {b}^{2}  - 4ac} }{2a}

Based on the information given from the question, we can deduce:

a = 1

b = 6

c = -5

Now we can substitute all these values into the formula to find x.

x =   \frac{ - 6 +  -  \sqrt{ {6}^{2}  - 4(1)( - 5)} }{2(1)}  \\  =   - 3 +  \sqrt{14}   \: or \:  - 3 -  \sqrt{14}

NARA [144]

9514 1404 393

Answer:

  B=\dfrac{T+9}{A}

Step-by-step explanation:

Add 9 to both sides of the equation, and divide by the coefficient of B.

  T = BA -9

  T +9 = BA

  (T +9)/A = B

We can rewrite that with B on the left:

  B = (T +9)/A

This is Pythagorean's Theorem, with one leg being 10 and the hypotenuse being 16.  Using those values in the theorem looks like this:
10^{2} + b^{2} = 16^{2}
and 100+ b^{2} =256
and b^{2} =256-100
so b^{2} =156
Take the square root of both sides to find that b = 12.5
