Answer:
x₁ = <u>5 + √11</u>
2
x₂ = <u>5 - √11</u>
Step-by-step explanation:
quadratic formula is given by
x = <u>-b ±√b² - 4ac</u>
2a
a = 2, b = -10, c = 7
x = <u>-(-10) ± √-10² - 4*2*7</u>
2*2
x = <u>10 ± √100 - 56</u>
4
x = <u>10 ± √44 </u> = <u>2(5 ± √11)</u> = <u>5 ± √11</u>
4 4 2
Answer:X=11/10
2x2-10x+7=0
<u><em>4</em></u>-10x+<u><em>7</em></u>=0
11-10x=0
-10x= -11
Divide both side by -10
-10x/-10. -11/-10
Answer= 11/10
