(x-5)(x+6)=0
Step-by-step explanation:
hehe i doing the smae unit rn.
if a=1 (which it does do ac factoring)
you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.
substitute 1x for -5x + 6x.
group the numbers into pairs and find their gcf's
x(x-5) 6(x-5)
since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.
FINAL: (x-5)(x+6) hope this helps
