x2 -7x +6=0 can be factorised by looking at the 7 and the 6 and looking for two numbers that can both add to give -7 and can multiply to give +6.
Possible factors for (numbers that will multiply to give) 6 are:
2 & 3
1 & 6
Now look at the possible sums from these possible factors:
2+3=5 not 7, and making one or more of these negative still won't result in a sum of 7 so we can rule those out.
1+6=7 Good so far! Now look at the sign. We need a negative 7. If both the 1 and the 6 are negative, it will give -7, which is what we are looking for.
-1 x -6 =6 because the two negatives cancel out, which is what we need, so the quadratic can be factorised as:
(x-1)(x-6)=0
(5x - 1)(x + 6)
2st4 + s2t2 - 9s5t + 21 The degree of a polynomial with more than one variable is the largest sum of the powers in any single term. So the degree of the given polynomial is 6 (-9s5t1; 5 + 1).
x2 + 7x + 6 = (x + 6) (x + 1)
44x^6 not 44x6 and 8x^5 not 8x5, my bad
(y+2)(y+3)
(x-2)(x-3)
It is: (x+1)(x+6) when factored
(5x - 1)(x + 6)
(x+6)(X+20)
(x - 6)(x - 3)
x+11x+30(x+5)(x+6)
(x - 3)(x + 6)
(x - 6)(x - 9)
n^2(n + 6)(n^2 - 6n + 36)
-2 and -6
(x + 6)(x + 2)
Yes.
