What is the x intercept of the graph of the equation
y=x•x-11x+24
1 answer:
Y = x² - 11x + 24
0 = x² - 11x + 24
x = <u>-(-11) +/- √((-11) - 4(1)(24))</u>
2(1)
x = <u>11 +/- √(121 - 96)</u>
2
x = <u>11 +/- √(25)
</u> 2
x = <u>11 +/- 5</u>
2
x = <u>11 + 5</u> x = <u>11 - 5</u>
2 2
x = <u>16</u> x = <u>6</u>
2 2
x = 8 x = 3
The x - intercept of the equation is equal to {8, 3}.
