Question

Which of the following are solutions to the equation below?

Check all that apply.

15x^2 - 44x + 32 = 0

A. x = 4/3
B. x = 4
C. x = 5/8
D. x = 8/5
E. x = 3/4
F. x = 8

Answer 1

quadratic equation \[\large\rm Ax^2+Bx+C=0\]
where
A=leading coefficient
B=coefficient of x variable
C= constant term
plugin these values into the quadratic formula
\[x=\frac{ - b \pm \sqrt{b^2-4ac} }{ 2a }\]

Answer 2

You can either solve by factoring or quadratic formula,

or just plug in each value one at a time, and see which result in zero.

Answer 3

or you can graph it https://www.desmos.com/
x values (x-intercept ,solution, zeros) where the graph intersects the x-axis
