expand (90-2x=90-(45))(45)

expand

(90 - 2 x = 90 - (45)) (45)

4050 - 90 x = - 1935

Solution steps

(90 - 2 x = 90 - (45)) (45)

= (45) (90 - 2 \cdot 90 = x - (45))

Distribute parentheses

= (45) \cdot 90 + (45) (- 2 x = 90) + (45) (- (45))

Apply minus-plus rules

+ (- a) = - a

(45) \cdot 90 - (45) \cdot 2 x = 90 - (45) (45)

Simplify

(45) \cdot 90 - (45) \cdot 2 x = 90 - (45) (45) : 4050 - 90 x = - 1935

4050 - 90 x = - 1935

\frac{- y ^{6} - 9 x ^{2} y ^{4} + 9 x ^{4} y ^{2} + x ^{6}}{( x ^{2} + y ^{2} ) ^{3}}

\frac{3 ( n - 1 )}{2 n}

\frac{4 ( 1 - x )}{3}

d x (2 x - cos (x))

(- x^{2} + 3 - e^{4 x - 3})^{2}
