Answer:
51
Step-by-step explanation:
11+(-7)^2-9 - original
11+49-9 - square the -7, since its in brackets the negative applies too and a negative x a negative = positive, so it ends up as 7x7+49
60-9 - add both positives 11+49=60
51 - subtract 9 from 60, 60-9=51
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.
<span>2x^2 + 3x + 0=0 </span>
<span>a=2, b=3, c=0 </span>
<span>b^2-4ac (In the next step just plug in your variables) </span>
<span>3^2 - 4(2)(0) </span>
<span>9 - 8(0) </span>
<span>9 - 0 </span>
<span>Your answer=9</span>
