Factoring:
ax**2 + bx + c
Step 1: Multiply coefficients of first and third terms
a∗c
1*54
Step 2: Factor product of coefficient of first and third term (a*c), choose 2
factors whose sum is the coefficient of the second term (b)
a∗c=d∗e
d+e=b
54=2*3*3*3
54=2*27
54=6*9
54=18*3
9+6=15
Step 3: Rewrite equation
ax**2 + dx + ex + c
x**2+ 9x+6x+54
Step 4: Factor sets of terms (first and second, third and fourth)
gx(hx + i) + j(hx + i)
x(x+9)+6(x+9)
where: g is the greatest common factor of a and d
where: j is the greatest common factor of e and c
where: h = a ÷ g, e ÷ j
where: i = d ÷ g, c ÷ j
Step 5: Combine Like terms:
(gx + j)(hx + 1)
(x+6)(x+9)

What is the answer to x2 15x 54?
This question does not make sense. If it should be X2 x 15X -54, the answer is: X2 -15X + 54 = (X - 6)(X -9)
How do you factor x squared plus 15X plus 54?
x2 + 15x + 54 = (x + 6)(x + 9) or (x + 9)(x + 6) since 6*9 = 54 and 6 + 9 = 15However, commutativity is implicit in deriving this factorisation so that the two factorisations are the same.or factor by groupingx2 + 15x + 54= x2 + 6x + 9x + 54= (x2 + 6x) + (9x + 54)= x(x + 6) + 9(x + 6)= (x + 6)(x + 9)
