Question

What are the x-intercept(s) of the graph of y − x2 = 11x + 30?

Answer 1

first put x^2 to the right side

y = x^2 + 11x + 30

now put y to zero because it is an x-intercept

0 = x^2 + 11x + 30

does that look familiar?

Answer 2

yes i think i understand

Answer 3

great! ^_^

Answer 4

so then -b/2a for the vertex, right?

Answer 5

uhmm idk those formulas sorry...i just remember the basics haha..maybe try asking again in the main question and someone who remembers it can answer :)
