Step-by-step explanation:
9m²+8m-6-7m²-3m+3
first write like terms
9m²-7m2+8m-3m-6+3
second ad subtract the terms
2m²+5m-3
factorize
2m²-m+6m-3
m(2m-1)+3(2m--1)
(m+3)(2m-1)
m=-3. m=1/2
There is no error on Jill's part. The teachers error was that she marked it wrong.
Answer:
x = -2
Step-by-step explanation:
x^2 + 4x + 4 = 0
quadratic formula:
-b +or- sqrt(b^2-4ac)/2a
-4 +/- sqrt ((-4)^2-4*1*4)/2*1
-4+/- sqrt(16-16) / 2
-4 +/- 0 / 2
-4/2
-2
