I am very desperate right now and I would be so happy for someone to help me. I have all the answers I just need step-by-step work to be shown. The subject is Factoring Expressions.
5a. 2x^2+11x+12 5b. 4x^2+7x+3 5c. 2x^2-7x+6

6a. 2x^2+7x-9 6b.3x^2-16x-12 6b. 4x^2+5x-6

Thank you so much to whoever answers this!

step-by-step explanation: s

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
