Which expression is equivalent to a2x2-2cx2 +a2y-2cy? (Polynomial Functions - Factoring)

lidiya [134]

Given:

The given expression is $a^2x^2-2cx^2+a^2y-2cy$

We need to determine the expression that is equivalent to the given expression.

Equivalent expression:

The equivalent expression can be determined by solving the expression.

Let us solve the polynomial function by factoring.

First, we shall group the expression.

Thus, we get;

$x^2(a^2-2c)+y(a^2-2c)$

Factoring out the common term $(a^2-2c)$ , we get;

$(x^2+y)(a^2-2c)$

Thus, the expression that is equivalent to the expression $a^2x^2-2cx^2+a^2y-2cy$ is $(x^2+y)(a^2-2c)$

Hence, the equivalent expression is $(x^2+y)(a^2-2c)$

Therefore, Option C is the correct answer.

Let u = <-3, -5>, v = <-3, 1>. Find u + v. (1 point)

Margaret [11]

You sum two vectors by summing the correspondent coordinates:

$u=(u_x, u_y),\ v=(v_x, v_y) \implies u+v = (u_x+v_x, u_y+u_y)$

So, you have

$(-3,-5)+(-3,1) = (-3-3, -5+1)=(-6, -4)$
