Please solve the factor of
f(x)= -x^2 + 2x +3
show workout

x = 3, -1

Step-by-step explanation:

By Middle term splitting,

=> -x² + 2x + 3 = 0

=> -x² + 3x - x + 3 = 0

=> -x (x - 3) -1 (x - 3) = 0

=> (x - 3) (-x -1) = 0

=> x = 3, -1

Hope it helps.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
