Find all the points where y - 4x=12 intersects 2 - y=2(x+2)2

LUCKY_DIMON [66]

Y=4x+12
y=-2(x+2)2+2=>y=-4x-4+2=-4x-2=>
y=-4x+2
Use the elimination property:
2y=14
y=7
Put y value back to the first equation: 7=4x+12, solve for x and -5=4xso x=-5/4
(-5/4,7)

Write the quadratic equation whose roots are 3 and -5, and whose leading coefficient is 2.

Rainbow [258]

$\begin{cases} x=3\implies &x-3=0\\ x=-5\implies &x+5=0 \end{cases}\qquad \implies\qquad a(x-3)(x+5)=\stackrel{0}{y} \\\\\\ a(\stackrel{F~O~I~L}{x^2+2x-15})=y\implies \stackrel{\textit{leading coefficient of 2}}{2(x^2+2x-15)}=y\implies 2x^2+4x-30=y$
