iris [78.8K]3 years ago
6 0
Here a=1, b= -5 and c= -3

so the discrim. is b^2 - 4(a)(c),   or   (-5)^2 - 4(1)(-3)  = 25 + 12 = 37.

Because the discrim. is +, you'll have 2 real, unequal roots.

The form y = mx+b is known as slope intercept form

m is the slope and b is the y intercept

Comparing y = (3/4)x - 1/2 to y = mx+b, we see that

Schach [20]
f(x)=x^{2} -12x+20
f(x)=0
xx^{2} -12x+20=0
Factoring:
(x-2)(x-10)=0
Two possible soolutions:

x-2=0 [tex]x=2

x-10=0
x=10

The zeros of the polynomial function are x=2 and x=10
