Use the table to identify the values of p and q that should be used to factor x^2+9x-10 as (x+p)(x+q)
2 answers:
X^2 + 9x -10 = (x -1)(x +10) = (x +(-1)) (x + 10)
p = -1 and q = 10
answer is A.
Answer with explanation:

From the table
Sum of term which contains coefficient of , x =9=-1+10
Constant term = -10= -1 × 10
⇒ (x+p)(x+q)=(x-1)(x+10)
Comparing , L HS and R HS
p= -1
q= 10
Option A:→ -1 and 10
