Question

помогите дам 80б СРОЧНО!

Answer 1

(p-q)(p+q)= p²-q²

(7+3y)(7-3y)= 49-9y²

(5a+8b)(5a-8b)= 25a²-64b²

(5x-10y)(5x+10y)= 25x²-100y²

(q+4p)(q-4p)= q²-16p²

(m+x²)(m-x²)= m²-x⁴

(x³-2y⁴)(x³+2y⁴)= x⁶-4y⁸

(0,1a-b)(0,1a+b)= 0,01a²-b²

(2y+3z)(2y-3z)= 4y²-9z²

(2a+x²)(2a-x²)= 4a²-x⁴

(x⁴-a⁵)(x⁴+a⁵)= x⁸-a¹⁰

(c⁴-d²)(c⁴+d²)= c⁸-d⁴

(0,3a-b³)(0,3a+b³)= 0,09a²-b⁶

(2x⁵-3y²)(2x⁵+3y²)= 4x¹⁰-9y⁴

(0,9y³+0,6x)(0,9y³-0,6x)= 0,81y⁶-0,36x²
