Simplify the expression. State any excluded values. x^ 2 - 36/42x - 7x^ 2

REY [17]

Consider the expression $x^2-\dfrac{36}{42}x-7x^2.$

This expression contains two terms with $x^2,$ group them:

$x^2-7x^2=x^2(1-7)=-6x^2.$

Now simplify term $\dfrac{36}{42}x=\dfrac{6}{7}x.$

Now $x^2-\dfrac{36}{42}x-7x^2=-6x^2-\dfrac{6}{7}x=6\left(-x^2-\dfrac{1}{7}x\right)=-6x\left(x-\dfrac{1}{7}\right).$

This expression is defined for all x.

If g(x)=7x²−4x−3 and h(x)=5x²−12x, find (h∘g)(1) FIRST BEST ANSWER BRAINLIEST

AURORKA [14]

Answer: See below

Step-by-step explanation:

$h\:\circ \:g=h\left(g\left(x\right)\right)$

$=5\left(7x^2-4x-3\right)^2-12\left(7x^2-4x-3\right)$

$=5\left(7x^2-4x-3\right)\left(7x^2-4x-3\right)-12\left(7x^2-4x-3\right)$

$=245x^4-280x^3-130x^2+120x+45-84x^2+48x+36$

Simplify:

$=245x^4-280x^3-214x^2+168x+81$
