Answer:
x=5 x=3
Step-by-step explanation:
x^2 – 8x + 15
What two numbers multiply to 15 and add to -8
-5*-3 = 15
-5 +-3 = -8
(x-5) (x-3) =0
Using the zero product property
x-5 =0 x-3 =0
x=5 x=3
Answer:
x=5 or x=3
Step-by-step explanation:
find two numbers that add up to the middle number (-8) and multiply to equal the last number (15)
in this case -5 and -3 add to be -8 and multiply to be 15
add these numbers in place of -8x
x^2-5x-3x+15 now add parentheses
(x^2-5x) (-3x+15) take out common factors
(x-5)(x-3) now make each set of parentheses equal to zero
x-5=0 x-3=0 now solve
x=5 x=3
