Answer:

Simplifying

(2x2 + -3x + 1)(x + -2)

Reorder the terms:

(1 + -3x + 2x2)(x + -2)

Reorder the terms:

(1 + -3x + 2x2)(-2 + x)

Multiply (1 + -3x + 2x2) * (-2 + x)

(1(-2 + x) + -3x * (-2 + x) + 2x2 * (-2 + x))

((-2 * 1 + x * 1) + -3x * (-2 + x) + 2x2 * (-2 + x))

((-2 + 1x) + -3x * (-2 + x) + 2x2 * (-2 + x))

(-2 + 1x + (-2 * -3x + x * -3x) + 2x2 * (-2 + x))

(-2 + 1x + (6x + -3x2) + 2x2 * (-2 + x))

(-2 + 1x + 6x + -3x2 + (-2 * 2x2 + x * 2x2))

(-2 + 1x + 6x + -3x2 + (-4x2 + 2x3))

Combine like terms: 1x + 6x = 7x

(-2 + 7x + -3x2 + -4x2 + 2x3)

Combine like terms: -3x2 + -4x2 = -7x2

(-2 + 7x + -7x2 + 2x3)

Following are calculation to the given eqution:

Given:

$\bold{(-m^2+6)+(-4m^2+7m+2)}$

To find:

Solve the equation.

Solution:

$\to \bold{(-m^2+6)+(-4m^2+7m+2)}\\\\\to \bold{-m^2+6-4m^2+7m+2}\\\\\to \bold{-5m^2+7m+8}\\\\\to \bold{-1(5m^2-7m-8)}\\\\$

Therefore, the final solution is " $-1(5 m^2-7m-8)$ ".

rodikova [14]

Answer: 7bb +19 ll ≥210

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The product of the number of hours he works babysitting (bb) and the amount he earns per hour (7); plus The product of the number of hours he works lifeguarding (ll) and the amount he earns per hour 19; must be higher or equal to the amount he must earn this week (210)
