Question

factorise 10x^2-14x^3+18x^4​

Answer 1

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\huge{\underline{\sf{\pink{Required\:Answer:}}}}$

$\: \sf{10x^2=2 \times 5 \times x \times x}$

$\:\sf{18x^3=2 \times 3 \times 3 \times x\times x\times x}$

$\: \sf{14x^4=2 \times 7 \times x \times x\times x\times x}$

Now,

$\: \sf{10x^2-18x^3+14x^4}$

$\:\rm{(2 \times x \times x \times 5)-(2 \times x \times x \times 3 \times 3 \times x)}$

$\:\sf{+ (2\times x \times x \times 7 \times x\times x)}$

$\:\: \sf{2\times x \times x \times [(5-(3 \times 3 \times x) +(7\times x \times x)] }$

$\:\: \sf{2x^2 \times (5-9x+7x^2) }$

$\:\: \sf{2x^2(7x^2-9x +5)}$
