B. -3 and 5
constants are the numbers without variables (the letters) and coefficients are the numbers with variables
<span>Trinomial Ax^2 + Bx + C is perfect square if:
A > 0
C > 0
B = ±2√A√C
36b^2 − 24b − 16
C < 0
4a^2 − 10a + 25
2√A√C = 2*2*5 = 20,
B = −10
16x^2 + 24x − 9
not perfect square,
C < 0
4x^2 − 12x + 9
perfect square:
A>0,
C>0,
2√A√C
= 2*2*3
= 12
= -B
= (2x − 3)^2
