Can someone me solve this . i forgot how to so if you could explain . x^2 + 10x - 2 = 0

So for this, I will be using the quadratic formula, which is , with a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, plug the numbers in their appropriate spots:

Next, solve the exponent and the multiplications:

Next, solve the addition:

Next, apply the product rule of radicals here and simplify the radical:

Next, divide:

*The above is your exact solution. Approximates (rounded to the hundreths) are below:

Next, solve the equation twice, once with the + symbol and once with the - symbol:

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
