Answer:
= (x+8)(x+1)
Step-by-step explanation:
The given expression is:
x2 + 9x + 8
First of all multiply the coefficient of first term with constant term
1*8 = 8
Now find any two numbers whose sum is the middle term and whose product is 8
8*1 = 8
8+1 = 9
This shows that 8 and 1 are those numbers.
Now break the middle term of the expression:
x^2+8x+x+8
Now take the common from first two terms and last two terms:
= x(x+8)+1(x+8)
= (x+8)(x+1)....
Answer:
(x + 1)(x + 8)
Step-by-step explanation:
Given
x² + 9x + 8
Consider the factors of the constant term ( + 8) which sum to give the coefficient of the x- term (+ 9)
The factors are + 1 and + 8, since
1 × 8 = 8 and 1 + 8 = 9, hence
x² + 9x + 8 = (x + 1)(x + 8) ← in factored form
