Solve the equation b^2-13b+36=0

b=4, 9

Step-by-step explanation:

b^2-13b+36=0

factor out the trinomial,

(b-4) (b-9) = 0

zero property

b-4=0, b-9=0,

b=0+4=4

b=0+9=9

Find two numbers that when they multiply, you get the third term,

which is 36 in this problem. And when they add up, you get the second term,

which is - 13 in this problem.
