Подставим $$ a=-3,42 $$ в выражение $$ (4-a)^{2}-a(a-26) $$ и найдем значение.
Evaluate the expression by following steps:
- step0: Evaluate:
  $$\left(4-a\right)^{2}-a\left(a-26\right)$$
- step1: Substitute:
  $$\left(4-\left(-3.42\right)\right)^{2}-\left(-3.42\left(-3.42-26\right)\right)$$
- step2: Add the numbers:
  $$7.42^{2}-\left(-3.42\left(-3.42-26\right)\right)$$
- step3: Subtract the numbers:
  $$7.42^{2}-\left(-3.42\left(-29.42\right)\right)$$
- step4: Convert the expressions:
  $$\left(\frac{371}{50}\right)^{2}-\left(-3.42\left(-29.42\right)\right)$$
- step5: Multiply the numbers:
  $$\left(\frac{371}{50}\right)^{2}-100.6164$$
- step6: Rewrite the expression:
  $$\frac{371^{2}}{50^{2}}-100.6164$$
- step7: Convert the expressions:
  $$\frac{371^{2}}{50^{2}}-\frac{251541}{2500}$$
- step8: Rewrite the expression:
  $$\frac{371^{2}}{50^{2}}-\frac{251541}{50^{2}}$$
- step9: Transform the expression:
  $$\frac{371^{2}-251541}{50^{2}}$$
- step10: Simplify:
  $$\frac{371^{2}-251541}{2500}$$
Значение выражения $$ (4-a)^{2}-a(a-26) $$ при $$ a=-3,42 $$ равно $$ -45.56 $$.
Значение выражения при $$ a=-3,42 $$ равно $$ -45.56 $$.
