Answer:
0.01
Step-by-step explanation:
<span>x^4-9x^2+ 14
=(x</span><span>^2 - 7)(x^2 - 2)
solve for x
</span><span>x^2-2 = 0</span><span>
</span>x^2 = 2
x = <span>+√<span> 2 </span></span> = + 1.4142 and x = -√ 2 = - 1.4142<span>
</span>x^2-7 = 0
x^2 = 7
x = + √ 7 = +2.6458 and x = - √ 7 = - 2.6458
answer: 4 solutions
x = +√ 2 = + 1.4142
x = - √ 2 = - 1.4142<span>
</span>x = + √ 7 = +2.6458
x = - √ 7 = - 2.6458
Answer:
first one is 3
second is 15
