Answer: x^2-5x-84
Step-by-step explanation:
(x+7)(x-12)=
x*x+(-12*x)+7x+(-84)=
x^2-12x+7x-84=x^2-5x-84
Answer:
-4
Step-by-step explanation:
You are trying to find which t value gives you the answer of 13. Set the equation equal to 13 and solve for t.
-2t + 5 = 13
-2t + 5 - 5 = 13 - 5
-2t = 8
-2t/-2 = 8/-2
t = -4

Answer:
(x + 5)(2x + 1)
Step-by-step explanation:
Given
2x² + 11x + 5
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 5 = + 10 and sum = + 11
The factors are + 10 and + 1
Use these factors to split the x- term
2x² + 10x + x + 5 ( factor the first/second and third/fourth terms )
= 2x(x + 5) + 1 (x + 5) ← factor out (x + 5 from each term
= (x + 5)(2x + 1) ← in factored form
