Ireally need it what are the x-intercepts of the quadratic function? f(x)=x2−3x−10 enter your answers in the boxes. and

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x²−3x)=10

Complete the square. Remember to balance the equation by adding the same constants to each side.

(x²−3x+2.25)=10+2.25

Rewrite as perfect squares

(x-1.5)²=12.25> (+/-)[x-1.5]=3.5

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

just pick what you think i need more time let me know if this
