For what values of p will the equation 5x2 - px +45 = 0 have equal roots

The two solutions are:

p = 30 and p = -30

Step-by-step explanation:

Given the equation

For the given quadratic equation

a=5, b=-p, c=45

b²-4ac = 0

(-p)² - 4(5)(45)=0

p²-900=0

p² = 900

p = ± 30

The two solutions are:

p = 30 and p = -30

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
