Solve the equation by factoring.
Delicious77 [7]

Factorizing an expression involves writing the expression in simpler forms

The values of z are z = \frac 15 or z=4

The equation is given as:

5z^2 - 21z + 4 = 0

Expand the equation

5z^2 - 20z -z + 4 = 0

Factorize the expression:

5z(z - 4) -1(z - 4) = 0

Factor out z - 4

(5z - 1)(z - 4) = 0

Split

5z -1 = 0 or z - 4 = 0

Solve for z

z = \frac 15 or z=4

Hence, the values of z are z = \frac 15 or z=4

If the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

Given,

The vertices of the triangle = J(-3,-5), K(-2,2) and L(1,-4)

We know,

In reflection in y axis (x,y)  will become (-x,y)

Then the vertices of the reflection in y axis = J(3,-5), K(2,2) and L(-1,-4)

Draw the triangle using the vertices.

Hence, if the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)
