Consider the trinomial x^2+10x+24
tino4ka555 [31]

Answer:

see explanation

Step-by-step explanation:

(a)

(x + 2)(x + 12) ← expand using FOIL gives

x² + 14x + 24 ≠ x² + 10x + 24

(b)

consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (+ 10)

the factors are + 6 and + 4 , since

6 × 4 = 24 and 6 + 4 = 10 , then

x² + 10x + 24 = (x + 6)(x + 4)

What is the value of 26+5-4*3
MatroZZZ [7]

You have to use PEMDAS (Parentheses Exponents Multiplication/Division Addition/Subtraction) to solve this,

Because you don't have any parenthesis or exponents you start with Multiplication/Division. This means you do 4*3 to get 26+5-12

Then, you move to Addition/Subtraction in which you complete left to right, So you do 26+5 to get 31-12

Finally you subtract 31-12 to get 19
