Write the quadratic equation whose roots are 6 and -5, and whose leading coefficient is 3

Step-by-step explanation:

Intercepts form of quadratic equation is

y= a(x-p) (x-q) where 'a' is the leading coefficient

p  and q  are the roots

Given that 6  and -5  are the roots

so p = 6  and q= -5

Leading coefficient a= 3

Plug in all the values in the equation

y= a(x-p) (x-q)

y= 3(x-6) (x-(-5))

y= 3(x-6) (x+5)

Now we  multiply the parenthesis

Multiply 3 inside the parenthesis

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
