Question

What are the roots of the equation x^2-10x+74=0x
2−10x+74=0 in simplest a+bia+bi form?

Answer 1

Quadratic equation

Explanation:

The formula is - b+- square root b^2 - 4ac all divided by 2a

a=1

b=-10

c=74

So substitute the values and remember to keep the value in a bracket so the outside operator affects it

-(-10)+- square root (-10)^2 - 4(1)(74) all divided by 2(1)

Giving you 2 answers of x as their is a positive and negative square roots

X=-138

X=

Answer 2

x= 38/5
