Form an equation whose roots are 1/2 and -1/3.
tensa zangetsu [6.8K]
Well a root means that y will equal zero when x is that root number. we are given the roots. So when x = 1/2 or -1/3 then y = 0.

it has to be quadratic with an x^2 since it has 2 roots. So we will write basic formula

y = (x + a) (x + b)

in this basic quadratic the opposite of a and b will be roots. this means negative a and negative b are roots or -a and -b are roots.

so we can fill in our roots for a and b if we want but.remember we.have to use the opposite of.our roots because we.use -a and -b.

so let's fill in our opposite.roots for.a and.b

y = (x + (-1/2)) (x + (-(-1/3)))

since I have two negatives in front of the 1/3 it becomes positive.. So

y = (x - 1/2)(x + 1/3)

this is an equation with those roots. You can multiply it out if necessary.

y = x^2 - 1/6x - 1/6

I think that's what it comes out to.

F(x) = x2 + 3x + 2 is shifted 2 units left, the result is g(x). What is g(x)?
Veronika [31]

Answer:

g(x)=x^2+7 x+12

Step-by-step explanation:

since f(x)=x^{2}+3 x+2

now we are given that this function f(X) is shifted 2 units to the left and we get a function g(x) this means

g(x)=f(x+2) since f(x+2) will shift the function f(x) 2 units to the left.

g(x)=(x+2)^{2}+3(x+2)+12

g(x)=x^2+4+4 x+3 x+6+2

hence, the function g(x)=x^2+7 x+12
