Another, simpler way of writing this would be: 4x + 3x - 7 x 2 + 6
To start, using order of operations, you would do 7 x 2 which equals 14.
So now you've got 4x + 3x - 14 + 6.
Because different terms are being used, we collect like terms.
First is 4x + 3x which equals 7x.
Then there's 14 + 6 BUT because before the 14 there is a minus sign, it becomes NEGATIVE 14. It should now look like -14 + 6 which equals -8.
Now the entire equation should look like 7x - 8.
I have simplified the equation, but you are in fact unable to factorise it because there are no common factors of 7 and 8.
(a + 6)(a + 4)
(m + 6)(m + 1)
It is: 6(4x+3)
It is: 3(x+2)
2x + 6 = 2(x+3)
(5x + 2)(x + 3)
It is 2(2x+3) when factorised
x2 + 6x = x*(x + 6)
