You need to find factors whose sum is 10 and product is 25. Here, it is a square, and the number is 5.
m^2 +10m +25 = (m+5)(m+5)
X - 4
(3x + 1)(x + 6)
(x + 12)(x + 7)
(x + 10)(x + 4)
x - 4 APEX
(X + 2)(X + 4) Factored
x2+14x+40 = (x+4)(x+10) when factored
(x-4)(x-1)
(x + 11) and/or (x - 6)
(x - 6)(x - 7)
(x - 4) or (x + 8)
To factor the trinomial (x^2 + 3x - 4), we look for two binomials that multiply to give this expression. The factors of (-4) that add up to (3) are (4) and (-1). Therefore, the binomials are ((x + 4)) and ((x - 1)), making ((x - 1)) a factor of the trinomial.
