Question

IV.MATCH THE FOLLOWING.



a) 4y²x-3y

b) -2xy(5x²-3)

c) 5x(x² - y² + xy)

(i) 20x²y-20x

(ii) 5x³-5xy² +5x²y

(iii) 4x²-9

d) (2x+3)(2x-3)

(iv) -12y³

e) 5x(4xy-4)

(v) -10x³y+6xy​

Answer 1

The above  equations are Solved by Quadratic equations and the solution is arrived by the following,

a) $4y^{2}$ × $-3y$ = $-12y^{3}$

b) $-2xy(5x^{2} -3)$ = $-10x^{3}y + 6xy$

c) $5x(x^{2} -y^{2} + xy)$ = $5x^{3} -5xy^{2} +5x^{2} y$

d) $(2x+3)(2x-3)$ = $4x^{2}-9$

e) $5x(4xy-4)$ = $20x^{2} y-20x$
