Question

(4-3x)(5x -4)

pls answer this question​

Answer 1

$\left(4-3x\right)\left(5x-4\right)$

$=4\cdot \:5x+4\left(-4\right)+\left(-3x\right)\cdot \:5x+\left(-3x\right)\left(-4\right)$

$=4\cdot \:5x-4\cdot \:4-3\cdot \:5xx+3\cdot \:4x$

$=-15x^2+32x-16$

Answer 2

Answer:

$-15x^{2} +32x-16$

Step-by-step explanation:

$(4-3x)(5x-4)\\=20x-16-15x^{2} +12x\\=-15x^{2} +32x-16 \\or\\=-1(-15x^{2} +32x-16)\\=15x^{2} -32x+16$
