Part 1) Use the quadratic formula to solve the equation.

4x^2−10x+5=0

we know that
the quadratic formula is

in this problem
a=4
b=-10
c=5



the answer Part 1) is



Part 2)  What are the zeros of the function f(x) =x^2+7x−18?

we have 
f(x)=x²+7x-18
equals to zero the function
x²+7x-18=0

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

x²+7x=18

Complete the square. Remember to balance the equation by adding the same constants to each side
x²+7x+12.25=18+12.25

Rewrite as perfect squares

(x+3.5)²=30.25-----> square root----> (+/-)[x+3.5]=5.5

(+)[x+3.5]=5.5---> x=5.5-3.5----> x=2

(-)[x+3.5]=5.5----> x=-9

the answer part 2) is

the zero of the function are

x=2 and x=-9
