Y=3x+2; x=0.5 what is the answer

y=3.5

x = (1-√61) / 6=-1.135

x = (1+√61) / 6 = 1.468

Step by step solution:

Step 1:

Equation at the end of step 1:

(3x2 - x) - 5 = 0

Step 2:

Trying to factor by splitting the middle term

2.1 Factoring 3x2-x-5

The first term is, 3x2 its coefficient is 3.

The middle term is, - x its coefficient is - 1.

The last term, "the constant", is - 5

Step-1 : Multiply the coefficient of the first term by the constant 3 • - 5 = - 15

Step-2 : Find two factors of - 15 whose sum equals the coefficient of the middle term, which is - 1.
