Answer:
No real solutions
Step-by-step explanation:
Given in the question an expression
√3x²- 4x + 34 + √3x² - 4x - 11 = 9
Let's solve your equation step-by-step.
Step 1
3.464102x² − 8x +23 = 9
Step 2
Subtract 9 from both sides.
3.464102x² −8x +23 − 9 = 9 − 9
3.464102x² −8x + 14 = 0
Step 3
Use quadratic formula
with
a=3.4641016151377544
b=-8
c=14
x =-b±√b²-4ac / 2a
x = 8±√64-4(3.46)(14) / 2(3.36)
x = 8±√64-4(3.46)(14) / 2(3.36)
x = 8±√-129.76 / 2(3.36)

Answer:
Step-by-step explanation:
Take 3x^2 = y
:- √y+34 - √y-11=5
squaring both sides
y+34 + y-11 - 2√y+34-y+11 = 25
2y +25 -25 = 2√y+34-y+11
2y=2√y+34+y-11
Squaring both sides
4y^2=4(45)
4y^2=2y-25
4y^2-2y+25=0
u will get the values of y
put √3x^2+4 instead of y and solve.
