Expand the left side:

(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2

Then a = 15 and b = 13, so a - b = 2.

$\large\text{Hey there!}$

$\mathsf{1.5x - 6=7.5}\\\mathsf{\bf{\underline{ADD}}}\mathsf{\ by\ 6\ on\ both\ of\ your\ sides}\\\mathsf{1.5x-6+6=7.5+6}\\\mathsf{Cancel\ out: -6+6\ because\ it\ equals\ 0}\\\mathsf{Keep:7.5+6\ because\ it\ helps\ us\ solve\ for\ your\ answer}\\\mathsf{7.5 + 6=13.5}\\\mathsf{We\ get: 1.5x=13.5}\\\mathsf{\bf{\underline{Divide}}}\mathsf{\ both\ sides\ by\ 1.5\ on\ your\ sides}\\\mathsf{\dfrac{1.5x}{1.5}=\dfrac{13.5}{1.5}}\\\\\mathsf{Cancel\ out: \dfrac{1.5x}{1.5}\ because\ it\ equals\ 1}$

$\mathsf{Keep: \dfrac{13.5}{1.5}\ because\ it\ gives\ you\ x}\\\\\mathsf{\dfrac{13.5}{1.5}=13.5\div1.5\rightarrow9}\\\\\\\boxed{\boxed{\mathsf{\bf{Your\ ANSWER: \boxed{\mathsf{x=9}}}}}}\checkmark$

Expanding and Simplifying Triple Brackets:<br> (4x + 6) (x - 3)<br> Please help!<br> Thankyou all! X

Otrada [13]

This would only be a double bracket...

but you do
(4x+6) (x-3)
F 4x * X = 4xsquared
O 4x* -3 = -12x
I. 6xX = 6x
L. 6*-3 = -18
collect like terms:
answer= 4x2 - 6x -18
the 4x is squared :)
