Answers
Answer:
additive
inverse of x2+15- =8x=0
Given : Step to Solve Quadratic Equation
To Find : Complete the missing Information
Solution:
x² + 15 = 8x translate into mathematical expression
x²+15-8x= 8x- 8x place polynomial on the side and set equation to zero by additive inverse property .
x²+15-8x = 0 write the equation
x²-8x+15= 0arrange the terms in descending order of its opponent .
(x - 5)(x - 3) = 0 Factor the polynomial
(x-5)=0 (x-3)=0 apply zero property .
x-5+5=0+5
x-3+3=0+3 solve for unknown by using additive inverse property.
x=5 or x=3 write the resulting equation
Final statement : the numbers are 3 , 5
