Answer:
Step-by-step explanation:
0= x2 – 2x – 3
a = 1, b = -2 and c = -3.
Answer:
equal to
Step-by-step explanation:
1/4x^2 = -1/2x + 2.....multiply everything by 4
x^2 = -2x + 8
x^2 + 2x - 8 = 0
(x + 4)(x - 2) = 0
x + 4 = 0
x = -4
x - 2 = 0
x = 2
solutions are : x = -4 or x = 2
Answer:
sometimes, if their average angle is over 45 degrees
never are 2 obtuse angles summing to 180 degrees
always. two 90 degree angles always sum to 180 which is a straight line
