(4x + 3)(4x - 3) Help pls

tekilochka [14]

Answer:

$16x^2-9$

Step-by-step explanation:

$\left(4x+3\right)\left(4x-3\right)$

We´ll Apply Difference Two Squares Formula:

$\left(a+b\right)\left(a-b\right)=a^2-b^2$

$\longmapsto$ $\left(4x+3\right)\left(4x-3\right)$

$\longmapsto$ $\left(4x\right)^2-3^2$

Apply exponent rule:

$\left(a\times \:b\right)^n=a^nb^n$

$\longmapsto$ $4^2x^2-3^2$

$\longmapsto$ $16x^2-9$

9x²-18x+14=0 quadratic equation

Ivahew [28]

Answer:

x∉R

Step-by-step explanation:

1) Solve the quadratic equation 9x²-18x+14=0 using x=(-b±√b²-4ac)/2a:

x=(-(-18)±√(-18)²-4×9×14)/2×9

2) Evaluate the power, calculate the product and multiply the numbers:

x=(18±√324-504)/18

3) Calculate the difference:

x=(18±√-180)/18

4) The square root of a negative number does not exist in the set of Real Numbers:

x∉R
