You want to multiply each term in the first set of parentheses by each term in the second set of parentheses:
2x * 5x = 10x^2
2x * 1 = 2x
3 * 5x = 15x
3 * 1 = 3
Add it all together to get: 10x^2 + 17x + 3

Well, this isn't an equation, just an expression to multiplicate and simplify.
(2x+3) (5x+1) =
(2x * 5x) + (2x * 1) + (3 * 5x) + (3 * 1) =
10x^2 + 2x + 15x + 3 =
10x^2 + 17x + 3
You forgot to multiply the x's in 2x * 5x.

wrong
10 x^2 + 2x+15x+3 = 10x^2 + 17x + 3

(2x + 3)(5x + 1) = 10x^2 + 2x + 15x + 3
= 10x^2 + 17x + 3

(2x+3) (5x+1) use FOIL
10x^2+2x+15x+3
10x^2+17x+3
No. the 10x should be 10x^2

Almost...
(2x)(5x) = 10x^2
So
10x^2 + 2x + 15x + 3
or 10x^2 + 17x + 3

No!
(2x+3) (5x+1)
10x^2+2x+15x+3
10x^2+10x+3
you forgot that 2x*5x = 10x^2

(2x+3) (5x+1) 2x * 5x= 10x^2
10x^2+15x+2x+3
10x^2+17x+3

no....
10x squared +2x+15x+3
so...
(10x^2)+17x+3

the 10x should be 10x², so it's
10x²+17x +3
