Answer 1

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
