Which of the following is a factor of 10x2 − 11x − 6?

stepladder [879]

Answer:

5x + 2

Step-by-step explanation:

Given

10x² - 11x - 6

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 = 10 × - 6 = - 60 and sum = - 11

The factors are - 15 and + 4

Use these factors to split the x- term

10x² - 15x + 4x - 6 ( factor the first/second and third/fourth terms )

= 5x(2x - 3) + 2(2x - 3) ← factor out (2x - 3) from each term

= (x - 3)(5x + 2) ← in factored form

Thus 5x + 2 is a factor of 10x² - 11x - 6

Simplify 36x^4 42x^7

Alja [10]

The first step to simplify this equation is to multiply the numbers
1512 $x^{4}$ × $x^{7}$
next,, youll multiply the terms with the same base by adding their exponents
1512 $x^{4+7}$
finally,, youll add the numbers together
1512 $x^{11}$
since you cant simplify any further,, the correct answer to your question is 1512 $x^{11}$
let me know if you have any further questions
