Find the product of (3x-4)(2x^2+2x-1)

lapo4ka [179]

Answer:

6x^3 - 2x^2 -11x +4

Step-by-step explanation:

(3x-4)(2x^2+2x-1)

Multiply 3x by the second term

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

6x^3 +6x^2 -3x

Multiply -4 by the second term

-4*(2x^2+2x-1)

-8x^2 -8x+4

Add these together, lining up the terms

6x^3 +6x^2 -3x

-8x^2 -8x+4

----------------------------------

6x^3 - 2x^2 -11x +4

What are the solutions to the quadratic equation -2x^2 + 6x + 3 = 0?

mario62 [17]

For this, we will be using the quadratic formula, which is $x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$ , with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: $x=\frac{-6+/-\sqrt{6^2-4*(-2)*3}}{2*(-2)}$

Firstly, solve the multiplications and the exponents: $x=\frac{-6+/-\sqrt{36+24}}{-4}$

Next, do the addition: $x=\frac{-6+/-\sqrt{60}}{-4}$

Next, your equation will be split into two: $x=\frac{-6+\sqrt{60}}{-4},\frac{-6-\sqrt{60}}{-4}$ . Solve them separately, and your answer will be $x=-0.436,3.436$

Solve the system of linear equations with substitution;

kvv77 [185]

Let's solve for x.
x
+
4
y
=
(
14
)
(
3
)
x
+
7
y
Step 1: Add -42x to both sides.
x
+
4
y
+
−
42
x
=
42
x
+
7
y
+
−
42
x
−
41
x
+
4
y
=
7
y
Step 2: Add -4y to both sides.
−
41
x
+
4
y
+
−
4
y
=
7
y
+
−

y
Step 3: Divide both sides by -41.
−
