Can anyone check this equation out for me please...
another way of writing out...
( 4 + b ) ( 3b - 2 )
is it
12b - 8 + 3bsq - 2b
which is
3b sq + 10b - 8
Help appreciated !!!
Thank you :-)
It looks good to me.
Thank you very much
To check if the equation (4 + b) (3b - 2) is equal to 3b^2 + 10b - 8, we can use the distributive property to expand the equation and simplify both sides.
First, distribute 4 to both terms inside the second set of parentheses:
(4 + b) (3b - 2) = (4 * 3b) + (4 * -2) + (b * 3b) + (b * -2)
= 12b - 8 + 3b^2 - 2b
Now, let's simplify this expression by combining like terms:
12b - 8 + 3b^2 - 2b = 10b - 8 + 3b^2
As we can see, the expanded equation is 10b - 8 + 3b^2, which is slightly different from the given expression 3b^2 + 10b - 8.
Therefore, the equation (4 + b) (3b - 2) is not equal to 3b^2 + 10b - 8.
