Exercise

$\left(2x+3\right)\left(x-7\right)=0$

Step-by-step Solution

1

Multiplying polynomials $2x+3$ and $x-7$

$\left(2x+3\right)x-7\left(2x+3\right)=0$
2

Multiply the single term $x$ by each term of the polynomial $\left(2x+3\right)$

$2x^2+3x-7\left(2x+3\right)=0$
3

Multiply the single term $-7$ by each term of the polynomial $\left(2x+3\right)$

$2x^2+3x-14x-21=0$
4

Combining like terms $3x$ and $-14x$

$2x^2-11x-21=0$

Final answer to the exercise

$2x^2-11x-21=0$
