Find the value of x (5x+12) (3x+16)

15x^2+116x+192

Step-by-step explanation:

(5x+12) (3x+16) multiply each term in the first parentheses by each term in the second parentheses

15Xx 3x+5Xx16+12x3x+12x16

15x^2+166X+192

                      ANSWER  15x^2+116+192

The chosen topic is not meant for use with this type of problem.

Step-by-step explanation:

The best way to try and solve is using the quadratic formula. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

( 5x + 12 ) x ( 3x + 16 )

Step one : use the distributive factor. To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

5x x 3x

5x x 16

12 x 3x

12 x 16

15x^2 + 80x + 36x + 192

Step two: Combine like terms

15x^2 + 116x + 192

Step three: Solve the equation for  x  by finding  a

,  b, and c of the quadratic then applying the quadratic formula.

x = - 12/5 , -16/3

-2 is the right
