2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
Answer:
193
Step-by-step explanation:
according to the question
w²=x²+v²-2xv.cos(<w)
w=√160²+150²-2.160.150.cos(77)°
w=√48100-48000cos(77°)
w=193
