FOR AN EXAM DUE TODAY!!! Simplify the polynomial. 3x – 2x2 + 4 – x2 + x + -

Mashutka [201]

Answer:

${ \tt{ \blue{ - {3x}^{2} + 4x + 4 }}}$

Step-by-step explanation:

${ \tt{3x - {2x}^{2} + 4 - {x}^{2} + x }} \\$

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

$= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\ = { \boxed{ \tt{ \: - {3x}^{2} + 4x + 4}}}$

A(4,-7) B(-2,1) find AB

Natali5045456 [20]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\A(\stackrel{x_1}{4}~,~\stackrel{y_1}{-7})\qquadB(\stackrel{x_2}{-2}~,~\stackrel{y_2}{1})\qquad \qquadd = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}\\\\\\AB=\sqrt{[-2-4]^2+[1-(-7)]^2}\implies AB=\sqrt{(-2-4)^2+(1+7)^2}\\\\\\AB=\sqrt{(-6)^2+8^2}\implies AB=\sqrt{36+64}\implies AB=\sqrt{100}\implies AB=10$
